FSImage should specify which dirs are missing when refusing to come up
----------------------------------------------------------------------
Key: HDFS-979
URL: https://issues.apache.org/jira/browse/HDFS-979
Project: Hadoop HDFS
Issue Type: Improvement
Components: name-node
Affects Versions: 0.22.0
Reporter: Steve Loughran
Priority: Minor
When {{FSImage}} can't come up as either it has no data or edit dirs, it tells
me this
{code}
java.io.IOException: All specified directories are not accessible or do not
exist.
{code}
What it doesn't do is say which of the two attributes are missing. This would
be beneficial to anyone trying to track down the problem. Also, I don't think
the message is correct. It's bailing out because dataDirs.size() == 0 ||
editsDirs.size() == 0 , because a list is empty -not because the dirs aren't
there, as there hasn't been any validation yet.
More useful would be
# Explicit mention of which attributes are null
# Declare that this is because they are not in the config
