[jira] [Updated] (IMPALA-10187) Event processing fails on multiple
events + DROP TABLE
[ https://issues.apache.org/jira/browse/IMPALA-10187?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Zoltán Borók-Nagy updated IMPALA-10187:
---------------------------------------
Description:
I've seen the following during interop testing:
Some DDL statements (ALTER TABLE + DROP) were executed via Hive on the same table.
Then CatalogD's event processor tried to refresh the table in its cache:

Impala tried to refresh the table on the first ALTER TABLE event, but since it's been already dropped we get a TableLoadingException (caused by NoSuchObjectException from HMS):

But the real problem is that event processing stops because of this error, i.e. no further events can be processed:
