Amazon Redshift JDBC Drivers Available on Cluster
Amazon Redshift JDBC drivers are now included at
/usr/share/aws/redshift/jdbc./usr/share/aws/redshift/jdbc/RedshiftJDBC41.jaris the JDBC 4.1-compatible Amazon Redshift driver and/usr/share/aws/redshift/jdbc/RedshiftJDBC4.jaris the JDBC 4.0-compatible Amazon Redshift driver. For more information, see Configure a JDBC Connection in the Amazon Redshift Management Guide. Java 8
Except for Presto, OpenJDK 1.7 is the default JDK used for all applications. However, both OpenJDK 1.7 and 1.8 are installed. For information about how to set
JAVA_HOMEfor applications, see Configuring Applications to Use Java 8.
Known issues resolved from previous releases
-
Fixed a kernel issue that significantly affected performance on Throughput Optimized HDD (st1) EBS volumes for Amazon EMR in emr-4.6.0.
-
Fixed an issue where a cluster would fail if any HDFS encryption zone were specified without choosing Hadoop as an application.
-
Changed the default HDFS write policy from
RoundRobintoAvailableSpaceVolumeChoosingPolicy. Some volumes were not properly utilized with the RoundRobin configuration, which resulted in failed core nodes and an unreliable HDFS. -
Fixed an issue with the EMRFS CLI, which would cause an exception when creating the default DynamoDB metadata table for consistent views.
-
Fixed a deadlock issue in EMRFS that potentially occurred during multipart rename and copy operations.
-
Fixed an issue with EMRFS that caused the CopyPart size default to be 5 MB. The default is now properly set at 128 MB.
-
Fixed an issue with the Zeppelin upstart configuration that potentially prevented you from stopping the service.
-
Fixed an issue with Spark and Zeppelin, which prevented you from using the
s3a://URI scheme because/usr/lib/hadoop/hadoop-aws.jarwas not properly loaded in their respective classpath. -
Backported HUE-2484
. -
Backported a commit
from Hue 3.9.0 (no JIRA exists) to fix an issue with the HBase browser sample. -
Backported HIVE-9073
