Siddharth Wagle commented on HDFS-14890:
----------------------------------------
Hi [~mohansella], the changes in HDFS-2470 do not affect datanode data dir.
Also, the clearDirectory() in the patch is called when NN is formatted, are you
testing this on a freshly deployed cluster or explicitly calling format?
If the set permission is failing can you provide some log details?
[~hirik] This Jira does address the NN failure, I am not sure if there is an
issue yet with setting permissions, waiting on some logs/exception.
