Hello CDH and Impala Users,   We are pleased to announce the release of Hive JDBC v2.5.12 and Impala JDBC v2.5.22. Hive JDBC v2.5.12 allows you to configure SSL separately from authentication and fixes the following issues: The getColumns() function returns an empty result set if it uses both schema and table restrictions, and the table restriction contains an escaped wildcard character. Query translation does not use the database context specified by a USE <database> query. The driver does not report an error when a MapReduce job fails on the server side during query execution.   Impala JDBC 2.5.22 fixes the following issues: The getColumns() function returns an empty result set if it uses both schema and table restrictions, and the table restriction contains an escaped wildcard character. Precision and scale for DECIMAL columns are reported incorrectly.   Query translation does not use the database context specified by a USE <database> query. These drivers work for versions of HiveServer2 in CDH 4.1 or higher and Impala 1.0 or higher. Previous drivers continue to work on the latest versions of HiveServer2 and Impala as well.   Getting started with the Cloudera Drivers: Read the Cloudera JDBC 2.5 driver for Hive release notes and installation guide.

We are pleased to announce the release of Cloudera Director 1.1.3. Cloudera Director is a simple, reliable, enterprise-grade way to deploy, scale, and manage Hadoop in the cloud, initially for Amazon Web Services (AWS). It is free to download and use, and supported for Cloudera Enterprise customers. This release fixes key bugs and includes the following: Uses lazy_itable_init when preparing ephemeral drives to speed up instance preparation.  This is useful for instances that have many large ephemeral drives, such as AWS D2 instances. Adds support for GUID Partition Table (GPT) root disk partitions. Allows custom AWS Identity and Access Management (IAM) endpoints. Changes the default Cloudera Manager and CDH versions to 5.3.3 instead of the latest version to ensure that compatible Cloudera Manager and CDH versions are used over the lifetime of Cloudera Manager. Corrects a typo for the d2.4xlarge instance type in virtualizationmappings. properties. No longer inadvertently upgrades Cloudera Manager packages that have been preinstalled on AMIs. Ensures that time is accurately synchronized by Network Time Protocol (NTP) prior to bootstrapping.  This improves cluster reliability and consistency.

CDH Optimization to avoid opening too many file descriptors during encryption DistCp fix to handle copying to root directory HDFS fixes for: Edit log corruption when append fails with a quota violation. Rolling upgrade restoring blocks from trash multiple times, which could cause. significant and unnecessary block churn. NameNode failover during high availability (HA) upgrade, which can cause the DataNode to finalize the upgrade. Null pointer exception (NPE) when NameNode transitions to active during startup. Incorrectly allowing HA NameNode to start in secure mode with HTTP wildcard address configured. Handling cache checks when encryption is enabled. YARN fixes for handling a race condition in the localizer, headroom calculation in the fair scheduler, and delegation token handling with DistCp. MapReduce fixes to handle heap sizes greater than 2 GB when expressed in bytes, MR2 regression from MR1 for running local jobs with -libjars command options, and hung jobs in certain scenarios. Minor HBase user interface and usability improvements, scanner improvements when not all values are returned, improved resource utilization in scanners, fixes to handle a broken truncate_preserve command in HBase shell, and deletion of HFiles used by a table cloned from a snapshot when that snapshot is deleted. Fixes for HiveServer2 memory leaks, column access for Parquet files, delegation token handling errors, and Hive on Spark bugs in Hive.

Clicking the "Revert to default" icon stores the default value as a user-defined value in the new configuration pages. Logging of command unavailable messages is improved. Various HDFS role migration improvements. HDFS/Hive replication no longer fails when replicating to a target cluster that runs CDH 4 and has Kerberos enabled. Cloudera Navigator fixes for the following issues: Link disappears when expanded. Operations on canary files should be filtered out. Hive views have same icon as Hive fields in lineage. Facet count should show (0) instead of (-) when there are no matching entities. Column lineage does not display. Kite dataset extraction fails when HDFS HA is enabled.
