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.

QHIVE-4040: It is a fix for an issue in
QHIVE-4053: It is a fix for an issue where the
QHIVE-4280: Hive jobs were failing with a Metaexception that included a timeout message. To resolve this issue, the SSH configuration parameters’ maximum value is increased on QDS servers.
QTEZ-335: It resolves an issue where the Tez Offline UI was inaccessible when
|27th March, 2019 (2:56 AM PST)||55.0.32||Enhancement||SPAR-3005:For the offline Spark clusters, only the event log files that are less than 400 MB are processed in the offline Spark History Server (SHS). This prevents high CPU utilization on the internal servers due to SHS.|
|Bug fix||SPAR-3391: Some paragraphs ran successfully but with a warning message during the first run. However, those paragraphs ran successfully without the warning on a re-run. This issue is fixed.|
|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
