Major Enhancements


QDS now offers Spark as a service and allows SparkCommand to be run via QDS. QDS also offers notebook interface for Spark. Every new account would have a pre-created Spark cluster. One can create additional clusters for Spark via Control Panel. QDS supports Spark SQL, Scala, Python and Shell commands to be run against Spark clusters. Spark SQL can use hive metastore for table metadata. QDS also supports autoscaling for Spark clusters.


Pig & HCatalog integration

QDS allows using Pig with HCatalog now. This allows using Hive Table definition with Pig.


RedShift Command

QDS now supports RedShift command and allows queries against RedShift.

Roles and Groups support is available in Analyze v2


GCE Enhancements

QDS now supports multiple clusters and fail scheduler for GCE. Node bootstrap can also be edited via UI. Support for more types of instances has been added.


All other minor changes and bug fixes are listed below


* HAD-304: Hadoop FairScheduler UI has been enhanced to show jobs that are queued for initialization. In addition, in the advanced mode, users can force Job Initialization

* HAD-297: Name Specified in Qubole Command is now used as part of the Hadoop Job Name for Shell Commands.

* HAD-335: Improvements in Hadoop JobTracker to speed up job scheduling by reducing contention on global JT lock

* HAD-182: S3 Objects with a trailing ‘/’ are now handled correctly by Hadoop S3 Native FileSystem.

* HAD-261: Map-Reduce should filter directories beginning with “_” character

* HAD-292: Hadoop Job may be limited in parallelism because of max mapper limits in it’s FairScheduler pool. This is now taken into account by the Hadoop auto-scaling logic.

* HAD-298: Uninitialized Hadoop jobs (in PREP state) are now terminated automatically when the jobclient is killed.

* QBOL-3739: Fixes to allow FairScheduler configuration to be pushed correctly from UI into running clusters.

* UI-1121: Cluster disallow termination is now available for presto cluster

* PRES-328: Handle bad ORC statistics

* PRES-313: Disable SSL when reading from S3

* PRES-308: Fix inserts into partitioned tables

* PRES-85: Allow dropping of hive tables from Presto
