Changes, enhancements, and resolved issues
-
This is a release to fix issues with Amazon EMR Scaling when it fails to scale up/scale down a cluster successfully or causes application failures.
Fixed an issue where scaling requests failed for a large, highly utilized cluster when Amazon EMR on-cluster daemons were running health checking activities, such as gathering YARN node state and HDFS node state. This was happening because on-cluster daemons were not able to communicate the health status data of a node to internal Amazon EMR components.
Improved EMR on-cluster daemons to correctly track the node states when IP addresses are reused to improve reliability during scaling operations.
SPARK-29683
. Fixed an issue where job failures occurred during cluster scale-down as Spark was assuming all available nodes were deny-listed. YARN-9011
. Fixed an issue where job failures occurred due to a race condition in YARN decommissioning when cluster tried to scale up or down. Fixed issue with step or job failures during cluster scaling by ensuring that the node states are always consistent between the Amazon EMR on-cluster daemons and YARN/HDFS.
Fixed an issue where cluster operations such as scale down and step submission failed for Amazon EMR clusters enabled with Kerberos authentication. This was because the Amazon EMR on-cluster daemon did not renew the Kerberos ticket, which is required to securely communicate with HDFS/YARN running on the primary node.
Newer Amazon EMR releases fix the issue with a lower "Max open files" limit on older AL2 in Amazon EMR. Amazon EMR releases 5.30.1, 5.30.2, 5.31.1, 5.32.1, 6.0.1, 6.1.1, 6.2.1, 5.33.0, 6.3.0 and later now include a permanent fix with a higher "Max open files" setting.
Hive column statistics
are supported for Amazon EMR versions 5.31.0 and later. Upgraded component versions.
EMRFS S3EC V2 Support in Amazon EMR 5.31.0. In S3 Java SDK releases 1.11.837 and later, encryption client Version 2 (S3EC V2) has been introduced with various security enhancements. For more information, see the following:
S3 blog post: Updates to the Amazon S3 encryption client
. Amazon SDK for Java Developer Guide: Migrate encryption and decryption clients to V2
. EMR Management Guide: Amazon S3 client-side encryption
.
Encryption Client V1 is still available in the SDK for backward compatibility.
New features
-
Lower "Max open files" limit on older AL2 [fixed in newer releases]. Amazon EMR releases: emr-5.30.x, emr-5.31.0, emr-5.32.0, emr-6.0.0, emr-6.1.0, and emr-6.2.0 are based on older versions ofAmazon Linux 2 (AL2), which have a lower ulimit setting for "Max open files" when Amazon EMR clusters are created with the default AMI. Amazon EMR releases 5.30.1, 5.30.2, 5.31.1, 5.32.1, 6.0.1, 6.1.1, 6.2.1, 5.33.0, 6.3.0 and later include a permanent fix with a higher "Max open files" setting. Releases with the lower open file limit causes a "Too many open files" error when submitting Spark job. In the impacted releases, the Amazon EMR default AMI has a default ulimit setting of 4096 for "Max open files," which is lower than the 65536 file limit in the latestAmazon Linux 2 AMI. The lower ulimit setting for "Max open files" causes Spark job failure when the Spark driver and executor try to open more than 4096 files. To fix the issue, Amazon EMR has a bootstrap action (BA) script that adjusts the ulimit setting at cluster creation.
If you are using an older Amazon EMR version that doesn't have the permanent fix for this issue, the following workaround lets you to explicitly set the instance-controller ulimit to a maximum of 65536 files.
Explicitly set a ulimit from the command line
Edit
/etc/systemd/system/instance-controller.service
to add the following parameters to Service section.LimitNOFILE=65536
LimitNPROC=65536
Restart InstanceController
$ sudo systemctl daemon-reload
$ sudo systemctl restart instance-controller
Set a ulimit using bootstrap action (BA)
You can also use a bootstrap action (BA) script to configure the instance-controller ulimit to 65536 files at cluster creation.
#!/bin/bash for user in hadoop spark hive; do sudo tee /etc/security/limits.d/$user.conf << EOF $user - nofile 65536 $user - nproc 65536 EOF done for proc in instancecontroller logpusher; do sudo mkdir -p /etc/systemd/system/$proc.service.d/ sudo tee /etc/systemd/system/$proc.service.d/override.conf << EOF [Service] LimitNOFILE=65536 LimitNPROC=65536 EOF pid=$(pgrep -f aws157.$proc.Main) sudo prlimit --pid $pid --nofile=65535:65535 --nproc=65535:65535 done sudo systemctl daemon-reload
With Amazon EMR 5.31.0, you can launch a cluster that integrates with Lake Formation. This integration provides fine-grained, column-level data filtering to databases and tables in the Amazon Glue Data Catalog. It also enables federated single sign-on to EMR Notebooks or Apache Zeppelin from an enterprise identity system. For more information, see Integrating Amazon EMR with Amazon Lake Formation in the Amazon EMR Management Guide.
Amazon EMR with Lake Formation is currently available in 16 Amazon Regions: US East (Ohio and N. Virginia), US West (N. California and Oregon), Asia Pacific (Mumbai, Seoul, Singapore, Sydney, and Tokyo), Canada (Central), Europe (Frankfurt, Ireland, London, Paris, and Stockholm), South America (São Paulo).
Known issues
-
Known issue in clusters with multiple primary nodes and Kerberos authentication
If you run clusters with multiple primary nodes and Kerberos authentication in Amazon EMR releases 5.20.0 and later, you may encounter problems with cluster operations such as scale down or step submission, after the cluster has been running for some time. The time period depends on the Kerberos ticket validity period that you defined. The scale-down problem impacts both automatic scale-down and explicit scale down requests that you submitted. Additional cluster operations can also be impacted.
Workaround:
-
SSH as
hadoop
user to the lead primary node of the EMR cluster with multiple primary nodes. -
Run the following command to renew Kerberos ticket for
hadoop
user.kinit -kt <keytab_file> <principal>
Typically, the keytab file is located at
/etc/hadoop.keytab
and the principal is in the form ofhadoop/<hostname>@<REALM>
.
Note
This workaround will be effective for the time period the Kerberos ticket is valid. This duration is 10 hours by default, but can configured by your Kerberos settings. You must re-run the above command once the Kerberos ticket expires.
-
When AtRestEncryption or HDFS encryption is enabled on a cluster that uses Amazon EMR 5.31.0 or 5.32.0, Hive queries result in the following runtime exception.
TaskAttempt 3 failed, info=[Error: Error while running task ( failure ) : attempt_1604112648850_0001_1_01_000000_3:java.lang.RuntimeException: java.lang.RuntimeException: Hive Runtime Error while closing operators: java.io.IOException: java.util.ServiceConfigurationError: org.apache.hadoop.security.token.TokenIdentifier: Provider org.apache.hadoop.hbase.security.token.AuthenticationTokenIdentifier not found
When you use Spark with Hive partition location formatting to read data in Amazon S3, and you run Spark on Amazon EMR releases 5.30.0 to 5.36.0, and 6.2.0 to 6.9.0, you might encounter an issue that prevents your cluster from reading data correctly. This can happen if your partitions have all of the following characteristics:
-
Two or more partitions are scanned from the same table.
-
At least one partition directory path is a prefix of at least one other partition directory path, for example,
s3://bucket/table/p=a
is a prefix ofs3://bucket/table/p=a b
. -
The first character that follows the prefix in the other partition directory has a UTF-8 value that’s less than than the
/
character (U+002F). For example, the space character (U+0020) that occurs between a and b ins3://bucket/table/p=a b
falls into this category. Note that there are 14 other non-control characters:!"#$%&‘()*+,-
. For more information, see UTF-8 encoding table and Unicode characters.
As a workaround to this issue, set the
spark.sql.sources.fastS3PartitionDiscovery.enabled
configuration tofalse
in thespark-defaults
classification.-
