[jira] [Created] (HDFS-2820) Add a simple sanity check for HA
config
Add a simple sanity check for HA config
---------------------------------------
Key: HDFS-2820
URL: https://issues.apache.org/jira/browse/HDFS-2820
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha, name-node
Affects Versions: HA branch (HDFS-1623)
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Trivial
If the user configures a shared edits dir, but doesn't configure the namenode addresses correctly, the NN will fail to start up in a very strange way.
I had this misconfiguration in one of my test clusters which was difficult to debug, even though I'm very familiar with the code. This patch is to add a simple sanity check so that if a user has the same misconfiguration, it will fail to start and given a more informative dump.
