> Block remain in COMMITTED but not COMPLETE cause by Decommission
> ----------------------------------------------------------------
>
> Key: HDFS-14429
> URL: https://issues.apache.org/jira/browse/HDFS-14429
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.9.2
> Reporter: Yicong Cai
> Assignee: Yicong Cai
> Priority: Major
> Attachments: HDFS-14429.01.patch, HDFS-14429.02.patch,
> HDFS-14429.03.patch, HDFS-14429.branch-2.01.patch,
> HDFS-14429.branch-2.02.patch
>
>
> In the following scenario, the Block will remain in the COMMITTED but not
> COMPLETE state and cannot be closed properly:
> # Client writes Block(bk1) to three data nodes (dn1/dn2/dn3).
> # bk1 has been completely written to three data nodes, and the data node
> succeeds FinalizeBlock, joins IBR and waits to report to NameNode.
> # The client commits bk1 after receiving the ACK.
> # When the DN has not been reported to the IBR, all three nodes dn1/dn2/dn3
> enter Decommissioning.
> # The DN reports the IBR, but the block cannot be completed normally.
>
> Then it will lead to the following related exceptions:
> {panel:title=Exception}

> {panel}
> And will cause the scenario described in HDFS-12747
> The root cause is that addStoredBlock does not consider the case where the
> replications are in Decommission.
> This problem needs to be fixed like HDFS-11499.
