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.

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.
