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.

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. Hue fixes for handling the correct number of rows with Hive queries returning data not encoded properly, errors during Oozie fork creation in the workflow editor, and Impala explain button. Fixes to handle crashes and errors with analytical functions, crashes due to missing newline at the end of the file and aggregate functions with empty select-project-join would crash Oozie automatically sets configurations so that Spark jobs are shown in the Spark History Server.
