Andrew Purtell commented on HBASE-8158:
---------------------------------------
The trunk/0.95 patch is not factored for hadoop-compat and this seems like the
sort of compatibility issue that was designed for. For 0.94 reflection makes
sense. For 0.95+, the same code in hadoop-compat-1 makes sense, for
hadoop-compat-2 we can assume JarFinder is there since Hadoop 2 code is >=
0.23.
I would commit this to 0.94 (ping [~lhofhansl]) and maybe take it on the chin
if there's test issues :-) because the patch looks good, the work on this issue
looks good, and there has been good review. However I would like to hold off
until a change goes in through trunk first. Please let me know your thoughts on
the above comment.
