-----------------------------------------
Summary: Reassign Master: moving the NameNode while NameNode HA is
enabled breaks HBase
Key: AMBARI-3735
URL: https://issues.apache.org/jira/browse/AMBARI-3735
Project: Ambari
Issue Type: Bug
Components: client
Affects Versions: 1.4.2
Reporter: Oleg Nechiporenko
Assignee: Oleg Nechiporenko
Fix For: 1.4.2
With NameNode HA enabled, move one of the NameNodes to another host.
During the final "Start all services" task of the Reassign Master wizard, HBase
service check fails.
This is because the Reassign Master wizard incorrectly sets *hbase.rootdir* in
*hbase-site.xml* to *hdfs://<new-namenode-host>/apps/hbase/data*.
When HA is enabled, the value of *hbase.rootdir* should always be
*hdfs://<nameservice-id>/apps/hbase/data*.
Also, Reassign Master does not handle
*dfs.namenode.https-address.<nameservice-id>.nn[1|2]* parameters in
*hdfs-site.xml* properly; it does not update the value to use the new NameNode
host. On the other hand *dfs.namenode.http-address.<nameservice-id>.nn[1|2]
parameters are handled properly already.
