Todd Lipcon commented on HADOOP-7115:
-------------------------------------
bq. Do we really want to set a precedent where we start patching Hadoop due to
specific vendor's implementation problems
Yes. In my opinion this is unavoidable for large scale systems.
But I agree with Koji that these workarounds should be configurable and
probably off-by-default.
