zengyongping updated HIVE-8440:
-------------------------------
Description:
In our environment Hiveserver handle approximately 15000 jobs per
day。Sometimes we found a large number of ETL tasks wait in our ETL schedule
queue to run。In this situation only few Hadoop Job running in Hadoop
cluster,many maps and reduces slots free.We view Hiveserver heap found
Hiveserver block a large number of query:
"pool-1-thread-17903" prio=10 tid=0x00007f89589c8000 nid=0x13865 waiting for
monitor entry [0x00007f893413b000]
