-----------------------------------
Summary: Refactor MetaStoreDirectSql by using getProductName
instead of querying DB to determine DbType
Key: HIVE-9741
URL: https://issues.apache.org/jira/browse/HIVE-9741
Project: Hive
Issue Type: Bug
Components: Metastore
Affects Versions: 1.0.0
Reporter: Xiaobing Zhou
Assignee: Xiaobing Zhou
Attachments: HIVE-9741.1.patch
MetaStoreDirectSql constructor is querying DB to determine dbType. which leads
to too many DB queries to make metastore slow or hanging if MetaStoreDirectSql
constructor is frequently called. This is to propose getProductName to get
dbType info.
