> Key: HDFS-10664
> URL: https://issues.apache.org/jira/browse/HDFS-10664
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ha, hdfs
> Affects Versions: 2.7.1
> Reporter: Amit Anand
> Assignee: Yuanbo Liu

> After a cluster is upgraded I see a mismatch in {{layoutVersion}} between NN
> VERSION file and JN VERSION file.
> Here is what I see:
> Before cluster upgrade:
> ==================
> {code}
> ## Version file from NN current directory
> namespaceID=109645726
> clusterID=CID-edcb62c5-bc1f-49f5-addb-37827340b5de
> cTime=0
> storageType=NAME_NODE
> blockpoolID=BP-786201894-10.0.100.11-1466026941507
> layoutVersion=-60
> {code}
> {code}
> ## Version file from JN current directory
> namespaceID=109645726
> clusterID=CID-edcb62c5-bc1f-49f5-addb-37827340b5de
> cTime=0
> storageType=JOURNAL_NODE
> layoutVersion=-60
> {code}
> After cluster upgrade:
> =================
> {code}
> ## Version file from NN current directory
> namespaceID=109645726
> clusterID=CID-edcb62c5-bc1f-49f5-addb-37827340b5de
> cTime=0
> storageType=NAME_NODE
> blockpoolID=BP-786201894-10.0.100.11-1466026941507
> layoutVersion=-63
> {code}
> {code}
> ## Version file from JN current directory
> namespaceID=109645726
> clusterID=CID-edcb62c5-bc1f-49f5-addb-37827340b5de
> cTime=0
> storageType=JOURNAL_NODE
> layoutVersion=-60
> {code}
> Since {{Namenode}} is what creates {{Journalnode}} {{VERSION}} file during
> {{initializeSharedEdits}}, it should also update the file with correct
> information after the cluster is upgraded and {{hdfs dfsadmin
> -finalizeUpgrade}} has been executed.
