Bug Fixes

  • HADTWO-2365: QDS now marks a Hadoop worker node as unhealthy if its root disk is full. This unhealthy node is eventually removed from the cluster.

  • HADTWO-2490: Fixes a problem that caused Spark shell commands to fail with the following error when the cluster was being downscaled: Unable to close file because the last block does not have enough number of replicas.

  • HADTWO-2506: Eliminates a race condition which caused data to be written on decommissioned HDFS Datanodes.
