Ayush Saxena commented on HADOOP-16077:
---------------------------------------
The extra RPC case shall come only in case of if -sp and -e parameter are used
together. Else it shall be only one . And Introducing in the getContentSummary
isn't a problem but thats part of Hadoop Common and usually we should prefer to
refrain from introducing into the common segment just for pourpose of HDFS and
moreover getContentSummary is quite an heavy operation as compared to
getStoaragePolicy. For ec policy it was added in the content summary since we
don't have getECpolicy in FileSystem it is only in HDFS.
So IMO that is generally not required, but if you insist on it I can extend, As
far as implementation is concerned that isn't that big , won't take any
considerable effort.
This case ,but will only come up only both ec and storage are to be fetched
together else both operations run fine.
But we need to be sure that doesn't effect object stores and all and doesn't
have much difference. because I wouldn't want to unnecessary problems to them
too.
An extra opinions won't hurt. [~surendrasingh] and [[email protected]] have
gone through the initial patches. Can you help in the context. If all have
similar thinking, I would extend the way suggested
[[email protected]] if patch needs to be changed. Would require your help
since this code is already in trunk. I guess got committed with your previous
commit.
