Review request for Ambari and Jonathan Hurley. Repository: ambari Description ------- There's a known issue in HDP 2.2.0.0 (HDFS-7533) where shutting down the datanode will not work because not all writers have responder running, but sendOOB() tries anyway. If the shutdown command fails with an output of "Shutdown already in progress", then Ambari should call datanode(action="stop"), which under the hood calls "hadoop-daemon.sh stop datanode" Diffs ----- ambari-server/src/main/resources/common-services/HDFS/2.1.0.2.0/package/scripts/datanode.py d8b8835 ambari-server/src/main/resources/common-services/HDFS/2.1.0.2.0/package/scripts/datanode_upgrade.py 29af5bd ambari-server/src/test/python/stacks/2.0.6/HDFS/test_datanode.py 2440145 ambari-server/src/test/python/stacks/2.3/common/test_stack_advisor.py da85cfc Diff: https://reviews.apache.org/r/35641/diff/ Testing ------- Uploaded the patch to a cluster performing a Rolling Upgrade and verified it worked. Unit tests passed. ---------------------------------------------------------------------- Total run:762 Total errors:0 Total failures:0 OK Thanks, Alejandro Fernandez
