Hyukjin Kwon edited comment on SPARK-23831 at 11/14/18 12:54 AM: ----------------------------------------------------------------- Because it caused a problem that Hive enabled session is restarted. I talked with [~yumwang] and looks it does not fix an actual usecase but the fix breaks one actual usecase. The fix and root causes were not perfectly understood so I rather reverted. Is there an actual case broken or fixed by this PR? If so, I don't object to restore this as I explained in the PR. was (Author: hyukjin.kwon): Because it caused a problem that Hive enabled session is restarted.
