Da Zhou commented on HADOOP-15954:
----------------------------------
Thanks for pointing out! Yes I realized some issues mentioned above so I was
working on the improvement.
[~ste...@apache.org]
*CustomIdentityTransformer*: Sure, I will add filesystem URI and close().
*transformListStatus(FileStatus[])*: I plan to remove this from interface
because it causes extra allocation, and this could be avoided by just declaring
sth like "*void transformUserAndGroupForWriteOperation(String[]userGroup))*"
and "*void transformUserAndGroupForReadOperation(String[]userGroup))*", so the
updated owner and group can be used to create FileStatus/AclStatus, as
mentioned by [~tmarquardt] for L117.
Will update the logic expression to improve readability.
*ITestAbfsIdentityTransformer*: will do the refactoring.
[~tmarquardt]
DefaultSPIdentityTransformer.java:
L84-92: Yes the use/group is inconsistent when exception happens when parsing
userGroupInfo in AzureBlobFileSystem and DefaultIdentityTransformer.
L107-114: once the owner meet the first if condition and get transformed to
localUser(which is already a shortUserName), then checking
shouldUseShortUserName() will be redundant, that is the reason it is put in the
else.
L117, L125-129, L157: these will be resolved. "void
transformListStatus(FileStatus[] entries)" makes sense.
