@Nasheb Ismaily Did you update new directory in Ambari - HDFS - configs - dfs.journalnode.edits.dir ? Did you restart JNs after copying the data? If you have done that, Clean /data1/hadoop/hdfs/journal on all three JNs and restart all JNs As HDFS user on any namenode , run hdfs namenode -initializeSharedEdits And then start your Namenodes .

@Dezka Dex Seems like you have old repos under /etc/yum.repos.d/. Please try this rm -f /etc/yum.repos.d/HDP* yum clean all And try install from Ambari. Ambari will create the repo files it needs.

ISSUE : When we click on Datanodes tab on Namenode UI, nothing happens.
ROOT CAUSE : This is happening because of https://issues.apache.org/jira/browse/HDFS-10888 and
https://issues.apache.org/jira/browse/HDFS-9193
which is fixed in Hadoop version 2.8. But HDP 2.5 is on Hadoop 2.7.
RESOLUTION/WORKAROUND : To resolve this, we can work around by
editing the below file on both the namenodes /usr/hdp/current/hadoop-hdfs-client/webapps/hdfs/dfshealth.js
and changing } else if (u.usedPercentage < 85) { to
} else if (v < 85) { We should be able to access datanode tabs after restarting namenode.
