-----------------------------------
satadru has commented on the revision "HIVE-3570 [jira] Hive changes for Optr
level stats".
@njain : I have done the changes and added an hook. Whenever I am executing
the hook from outside(ie hive cli) everything works fine. But when it is run
from the "ant test -Dtestcase=..." command, the Counter object in the
Operator.java coming as null. (Probable reason: the unit test is not executing
the query in actual hadoop cluster, without which counters are always null).
Please suggest if there is any way to get around this problem. I tried
searching for unit test involving counters in Operator.java, but couldn't find.
