[jira] [Created] (HIVE-18017) HS2 materialized view registry init
loading all tables from metastore
Songzhi Liu created HIVE-18017:
----------------------------------
Summary: HS2 materialized view registry init loading all tables from metastore
Key: HIVE-18017
URL: https://issues.apache.org/jira/browse/HIVE-18017
Project: Hive
Issue Type: Bug
Components: HiveServer2, Metastore
Affects Versions: 2.3.0, 2.2.0, 2.1.0
Environment: Hadoop 2.7.3 on EMR
Reporter: Songzhi Liu
We're pointing the hive to a remote MySQL metastore with tons of DBs and tables (10k+ tables). When HS2 starts it tries to init the materialized views and currently the metastore API tries to do a full load for every database. It times out after 20 min then HS2 starts without loading MV.
