Manoj Govindassamy commented on HDFS-11499: ------------------------------------------- [~lukmajercak], Are you referring to the timeout in TestDecommission#testDecommissionWithOpenFileAndDatanodeFailing() which was part of the patch v01 ? In the patch v02 I added Maintenance State related test. Not sure, if extending the timeout for the failed test is going to solve the problem. Because, the nodes didn't move to DECOMMISSIONED state as the test is expecting . {noformat} 2017-03-06 23:33:49,462 [Thread-782] INFO hdfs.AdminStatesBaseTest (AdminStatesBaseTest.java:waitNodeState(342)) - Waiting for node 127.0.0.1:33069 to change state to Decommissioned current state: Decommission In Progress 2017-03-06 23:33:49,462 [Thread-782] INFO hdfs.AdminStatesBaseTest (AdminStatesBaseTest.java:waitNodeState(342)) - Waiting for node 127.0.0.1:33069 to change state to Decommissioned current state: Decommission In Progress [test timeout] 2017-03-06 23:33:49,486 [main] INFO hdfs.MiniDFSCluster (MiniDFSCluster.java:shutdown(1951)) - Shutting down the Mini HDFS Cluster {noformat} > Decommissioning stuck because of failing recovery > ------------------------------------------------- > > Key: HDFS-11499 > URL: https://issues.apache.org/jira/browse/HDFS-11499 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs, namenode > Affects Versions: 2.7.1, 2.7.2, 2.7.3, 3.0.0-alpha2 > Reporter: Lukas Majercak > Assignee: Lukas Majercak > Labels: blockmanagement, decommission, recovery > Fix For: 3.0.0-alpha3 > > Attachments: HDFS-11499.02.patch, HDFS-11499.patch > > > Block recovery will fail to finalize the file if the locations of the last, > incomplete block are being decommissioned.
