Himanshu Vashishtha commented on HBASE-8211:
--------------------------------------------

Thanks for the review Matteo.
bq.  do you plan to port the HBaseFileSystem and HLogFileSystem to trunk? this 
patch seems to cover code more than the one in HBASE-8156.
Yes, trunk has the abstraction for fs calls, and its still moving in that 
direction. That's why I didn't change other places.
I don't think that 0.94 will see those changes, so, I tried to cover up all 
possible cases here. I do think that HBaseFileSystem/HLogFileSystem should be 
good for trunk too. Shall I patch it up?

re: Snapshot: yes, that's what i meant by resilent to failures in the above 
comment.

> HBase-8156 is for adding support for retrying non-idempotent operations. This 
> is useful in case NN is suffering from n/w hiccups, etc. This jira is to add 
> similar support for 0.94.x branch.
