Subject [jira] [Commented] (HDFS-5248) Checkpointing fails in uploading the Image to the Namenode if the merge requires more than 10 hours in secure cluster

Benoy Antony commented on HDFS-5248:
------------------------------------

The direct caller doesn't do the doAs. The doAs is made during the initialization.  Refactoring
it will be a good idea , but involves more code changes.
