> We start journalNode before Reconfigure HDFS in NameNode HA wizard in branch-1.4.2 (fixed
in trunk). JournalNode reads the property _dfs.journalnode.edits.dir_ from hdfs-site.xml before
HA related properties are configured in the wizard. 
> * In normal scenario, the value of  _dfs.journalnode.edits.dir_ is /grid/0/hdfs/journal
 even before the HA related properties are added as it is present in HDP-2.0.6 stack definition.
> * In the upgrade scenario from HDP-1.X stack to HDP-2.X, we do not add the property _dfs.journalnode.edits.dir_
in hdfs-site.xml. So JournalNode While starting doesn't find the property and puts all namenode
edits data in the default path _/tmp/hadoop/dfs/journalnode_. After that HA wizard adds the
property _dfs.journalnode.edits.dir_ = /grid/0/hdfs/journal in hdfs-site.xml. 
> * Next time when journalNode is restarted it doesn't find the namenode edits data as
the path stated by property _dfs.journalnode.edits.dir_ is reconfigured.
