--------------------------------------
Summary: HDFS service check failed after HA enabled on upgraded
(1.3.2->1.3.3->2.0.6) cluster.
Key: AMBARI-4039
URL: https://issues.apache.org/jira/browse/AMBARI-4039
Project: Ambari
Issue Type: Bug
Affects Versions: 1.4.2
Reporter: Jaimin D Jetly
Assignee: Jaimin D Jetly
Fix For: 1.4.2
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 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.
