Ashutosh Chauhan commented on HCATALOG-154:
-------------------------------------------
bq. fixed race condition and moved resolution outside of getOutputLocation
since output is intermediate.
Sorry, but I am having difficulty in following what was the problem originally
which patch is fixing. How can both bulkOSD and directOSD both return path for
getOutputLocation() I thought only one of them will be active at a time and if
so there is no possibility of race condition. Also, both of them now returns
null. Earlier, they were returning valid strings, how come then it was working
earlier and will continue to work. Also, what do you mean by intermediate
output, I thought these formats always deal with end user data and not with
intermediate data between map and reduce.
