Zoltan Haindrich commented on HIVE-16256:
-----------------------------------------
I checked this with:
{code}
mvn install -Pitests -Dtest=TestCliDriver -Dqfile=updateAccessTime.q,comments.q
-DskipSparkTests
{code}
and it failed with this issue...It seemed to me that
{{QTestUtil#clearTestSideEffects}} have tried to restore the original value.
I think this might be something possibly serious...
{{QTestUtil#clearTestSideEffects}} should have been able to clear out
{{hive.exec.pre.hooks}} to the default; but seems like it wasn't able to...it
might be some loose {{HiveConf}} instance buried somewhere - which may cause
more troubles in the future, since it doesn't necessarily belong to the current
session...my current guess is that it will be inside the explain logic
somewhere...
