|Date and time of release||Version||Change type||Change|
|27th Sep, 2019 (04:36 AM PST)||56.0.158||Enhancement||PRES-2791: Qubole has ported open-source changes that are related to improvements in S3 reads to Qubole Presto 0.208 version. For more information, see Faster S3 reads.|
PRES-2961: In an IAM-Role-based account, the issue where incorrect IAM-Role info had been sent to Presto has been resolved now.
PRES-2999: The NullPointerException when local memory limits are exceeded and a leak in operator peak memory computations in Presto version 0.208 queries have been resolved now.
PRES-3009: The issue where the Presto coordinator disk was filling up due to presence of RubiX logs in the autoscaling
log file has been resolved.
|Bug fix||ACM-5664: Fixed the caching issue of the cluster list in the Analyze (Workbench (beta) UI page.|
|Bug fix||ACM-5616: Status checking of Spot requests has been made more robust by doing retries for DescribeSpotInstanceRequests in case of the RequestResourceCountExceeded error.|
|Bug fix||QHIVE-4798: Fixed an issue which can lead to a memory leak in HiveServer2 JVM when a large number of concurrent applications are running on a given cluster.|
|Bug fix||ACM-5689: Fixed an issue where the default Hadoop cluster did not start during the AWS test drive signup.|
ACM-5266: Qubole supports
ACM-5413: Qubole supports
ACM-5558: During provisioning of nodes on a running heterogeneous cluster, Qubole tries providing instance types set in the heterogeneous configuration before falling back to On-Demand instances. For more information, see Additional Permissions.
ACM-5532: During the scrub run that is removing dead nodes for a cluster, there were nodes that were unreachable. This resulted in performance issues. To resolve this issue, Qubole terminates such nodes that cannot be connected. Via Support.
HADTWO-2098: In some cases, the scrub run did not remove dead nodes from a cluster. It happened as the scrub run connected to dead nodes as well through SSH to check on the node bootstrap completion. To resolve this issue, Qubole has improved the scrub run process, which does not connect to a dead node registered in the ResourceManager. This helps removing dead nodes that remained in the cluster and prevents such dead nodes from remaining in the cluster unlike before.
|22 Aug, 2019 (5:40 AM PST)||56.0.120||Enhancement||

PRES-2474: The optimization to speed up queries on
PRES-1373: This is a fix for an issue where the retry operation was not working on the failed Presto queries. Retries work on the failed Presto queries now. As part of the fix, retries are configurable for Presto queries that run on the QDS platform.
Configuring retries will just do a blind retry of a Presto query. This may lead to data corruption for non-Insert Overwrite Directory (IOD) queries.
PRES-2306: Fixed a bug where the Usage page on the QDS UI did not show the Presto query’s bytes read statistics.
PRES-2493: Fixed the data loss issue in the Hive connector when writing bucketed sorted table in Qubole Presto 0.208 queries.

|Bug fix||TOOLS-1139: The previous docker version had security vulnerabilities, which could allow malicious containers to
gain root-level privileges on the host. To resolve security vulnerabilities of the previous docker version, the
latest patch version of
