Tsuyoshi Ozawa commented on TEZ-2607:
-------------------------------------
I've found that we need a hack in a tricky way to embed SIMD-based bitonic
merge into Tez code. I'm designing it, but we can split the bottleneck into 2
phases - sorting phase(Text#compare in the figure), doing this on this jira,
and swapping phase(IntBuffer#get/IntBuffer#put), creating TEZ-2746 for
addressing the issue.
