Ayush Saxena commented on HDFS-15221:
-------------------------------------
Thanx [~hadoop_yangyun] for the patch. In case of any exception while getting
the effective filesystem, the getEffectiveFileSystem shall be null, In that
scenario, you are returning true, Is that intentional, In that case, do you
want to ignore this conf? Any pointers here. I think we should return false in
that case.
Apart things look good,
>From the reviewers end, Anyone following this up? or any further comments? I
>am at the stage of concluding this. Let me know, if anyone is reviewing or
>tend to do so. I will hold this...
> Add checking of effective filesystem during initializing storage locations
