> 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: 2.9.0, 3.0.0-alpha3
>
> Attachments: HDFS-11499.02.patch, HDFS-11499.03.patch,

> Block recovery will fail to finalize the file if the locations of the last,
> incomplete block are being decommissioned. Vice versa, the decommissioning
> will be stuck, waiting for the last block to be completed.
> {code:xml}
> org.apache.hadoop.ipc.RemoteException(java.lang.IllegalStateException):
> Failed to finalize INodeFile testRecoveryFile since blocks[255] is
> non-complete, where blocks=[blk_1073741825_1001, blk_1073741826_1002...
> {code}
> The fix is to count replicas on decommissioning nodes when completing last
> block in BlockManager.commitOrCompleteLastBlock, as we know that the
> DecommissionManager will not decommission a node that has UC blocks.
