Swapan Shridhar updated AMBARI-19116:
-------------------------------------
Description:
- Currently, hive2/HiveServer2 (HSI) heap size is ket same as that of
hive/HiveServer2.
Required:
- Hive2/HiveServer2 (HSI) heap size calculations to be based on LLAP
concurrency.
{code}
= min(max(2GB, 400*LLAP concurrency (Tez sessions)), 3/8 * <HS2 host total
RAM>)
{code}
*Side fix:* Also, updated "hive.llap.daemon.queue.name" and
"hive.server2.tez.default.queues" config values to one of the existing leaf
queues, in case of HSI being turned on and config values have queue names which
no more exist. The scenario can happen when, say :
- HSI was ON and the above 2 configs has queue name 'XYZ'.
- HSI was then turned off.
- Capacity Scheduler queues were changed and 'XYZ' queue was deleted.
- The above configs without this fix will otherwise show stale/non-existing
queue name.
