> Block replication not proceeding after pipeline recovery --

> Key: HDFS-10780
> URL: https://issues.apache.org/jira/browse/HDFS-10780
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs

>
> TestDataNodeHotSwapVolumes occasionally fails in the unit test
> testRemoveVolumeBeingWrittenForDatanode. Data write pipeline can have issues
> as there could be timeouts, data node not reachable etc, and in this test
> case it was more of induced one as one of the volumes in a datanode is
> removed while block write is in progress. Digging further in the logs, when
> the problem happens in the write pipeline, the error recovery is not
> happening as expected leading to block replication never catching up.
