NameNode format doesn't pick up dfs.namenode.name.dir.NameServiceId configure
-----------------------------------------------------------------------------
Key: HDFS-3013
URL: https://issues.apache.org/jira/browse/HDFS-3013
Project: Hadoop HDFS
Issue Type: Bug
Components: ha, name-node
Affects Versions: 0.23.0, HA branch (HDFS-1623)
Reporter: Mingjie Lai
One problem I observed at HA branch is that namenode -format doesn't pick up
the right configured dfs.namenode.name.dir.NameServiceId. In this case,
``namenode -format'' will format the default directory instead of the
configured one, while namenode will use the correct one.
The root cause is that NameNode.initializeGenericKeys() is only invoked at the
NameNode constructor. So it doesn't get called by static methods like format
and finalize.
