-----------------------------------
Summary: Add additional diagnostic logging in
DiskChecker::mkdirsWithExistsCheck()
Key: HDFS-4668
URL: https://issues.apache.org/jira/browse/HDFS-4668
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Eugene Koontz
Assignee: Eugene Koontz
Priority: Minor
While working on debugging a job, I had some need to understand how
mkdirsWithExistsCheck() works. It's a bit complex so I added some logging
statements at DEBUG level to understand what was going on. I also added an
ERROR-level message if a directory cannot be created.
