-----------------------------------------
Summary: ObjectStore.setConf() is doing dangerous work while
holding global lock
Key: HIVE-19177
URL: https://issues.apache.org/jira/browse/HIVE-19177
Project: Hive
Issue Type: Bug
Components: Metastore
Affects Versions: 2.0.2, 3.0.0, 3.1.0
Reporter: Alexander Kolbasov
The {{ObjectStore.setConf()}} function grabs static {{pmfPropLock}} and then
calls {{initialize}} which goes through DataNucleus, accesses database, waits
on DB thread pools, retries with sleep, etc, all while holding the lock.
This is rather dangerous and expensive since no one else can call setConf at
the same time on a different instance. All of these should be done without
holding the lock.
[~vihangk1] FYI.
