[jira] [Updated] (IMPALA-10648) Invalidate catalogd cache for non
transactional tables when create/alter/drop HMS apis are accessed
[ https://issues.apache.org/jira/browse/IMPALA-10648?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sourabh Goyal updated IMPALA-10648:
-----------------------------------
Description:
IMPALA-10613 introduced changes to expose table/partition metadata stored in catalog cache over HMS APIs.
In this task, we invalidate the non transactional table from cache if HMS DDL apis like create/alter/drop table/partition are accessed from catalogd's metastore server. Any subsequent get table request fetches the table from HMS and also loads it in cache. This ensures that any get_table/get_partition requests after ddl operations on the same table return the most updated table
