Hi, all
When I try hiveContext.hql("drop table if exists abc") where abc is a non-exist
table
I still received an exception about non-exist table though "if exists" is there
the same statement runs well in hive shell
Some feedback from Hive community is here:
https://issues.apache.org/jira/browse/HIVE-7458
“Your are doing hiveContext.hql("DROP TABLE IF EXISTS hivetesting") in Scala
schell of the Spark project.
What this shell is doing ? Query to remote metastore on non existing table (see
on your provided stack).
The remote metastore throws NoSuchObjectException(message:default.hivetesting
table not found)because Spark code call
HiveMetaStoreClient.getTable(HiveMetaStoreClient.java:854) on non-existing
table. It's the right behavior.
You should check on Spark code why a query is done on non existing table.
I think Spark does not handle well the IF EXISTS part of this query. Maybe you
could fill a ticket on Spark JIRA.
BUT, it's not a bug in HIVE IMHO.”
My question is the DDL is executed by Hive itself, doesn’t it?
Best,
