I'll do a port for 2.0 branch. > NPE in FSNamesystem.commitBlockSynchronization() > ------------------------------------------------ > > Key: HDFS-5077 > URL: https://issues.apache.org/jira/browse/HDFS-5077 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Affects Versions: 2.0.5-alpha > Reporter: Konstantin Shvachko > Assignee: Plamen Jeliazkov > Attachments: HDFS-5077_2.patch, HDFS-5077_3.patch, HDFS-5077.patch > > > NN starts a block recovery, which will synchronize block replicas on > different DNs. In the end one of DNs will report the list of the nodes > containing the consistent replicas to the NN via commitBlockSynchronization() > call.
