Zoltan Haindrich commented on HIVE-18036:
-----------------------------------------

[~k0b3rit]: could you please also remove the ErrorMsg.STATISTICS_CLONING_FAILED error message?
It looks like in ql/src/java/org/apache/hadoop/hive/ql/optimizer/stats/annotation/StatsRulesProcFactory.java there's 3 more places where its being catched :)

> {{Statistics}} and {{ColStats}} implements cloneable; however they never throw clonenotsupported; and this causes try / catch blocks which are just noise
