Suresh Srinivas commented on HDFS-4434:
---------------------------------------
bq. If the directory denies access, then we should ensure that no operation
will expose the path names because the user isn't supposed to be able to see
them.
Agreed. I am planning to open a jira to ensure all the methods make consistent
checks. I will make the required change to no divulge the complete path after
that.
bq. Does lease renewal work for inode paths?
renewLease() operation currently takes only clientName. I think we should
change this method to add path along with the clientName. I plan on doing this
in another jira. Once that is done, I plan on making changes to allow inode
path after that jira.
