-----------------------------------
Summary: hive.exec.parallel=true w/ Hive 0.13/Tez causes
application to linger forever
Key: HIVE-7237
URL: https://issues.apache.org/jira/browse/HIVE-7237
Project: Hive
Issue Type: Bug
Components: Tez
Affects Versions: 0.13.0
Environment: HDP 2.1, Hive 0.13, SLES 11, 128GB data nodes, ORC SNAPPY
Reporter: Douglas Moore
set hive.exec.parallel=true; will cause the Yarn application instance to linger
forever. set hive.exec.parallel=false, the application goes away as soon as
hive query is complete. The underlying table is an ORC store_sales table
compressed with SNAPPY.
{code}
hive.exec.parallel=true;
select * from store_sales where ss_ticket_number=5741230 and ss_item_sk=4825
{code}
The query will run under Tez and finish << 30 seconds.
After 30-40 of these jobs the cluster gets to a point where no jobs will finish.
