[jira] [Updated] (HIVE-21807) Provide a variant of IMetaStoreClient.createTable() that returns populated Table

     [ https://issues.apache.org/jira/browse/HIVE-21807?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Fredy Wijaya updated HIVE-21807:
--------------------------------
    Description: 
Currently https://github.com/apache/hive/blob/6664c44c795e467c08c79948270409f03a86d8c2/standalone-metastore/metastore-common/src/main/java/org/apache/hadoop/hive/metastore/IMetaStoreClient.java#L1678-L1679 does not provide a way to return a create table timestamp and many other information from the Table. Calling IMetastore.getTable() isn't an atomic operation and can be slightly racy.

By having a variant of IMetastoreClient.createTable() that returns a populated Table, we can make this operation atomic and avoid any race condition.
