Vineet Garg commented on HIVE-18852: ------------------------------------ +1 > Misleading error message in alter table validation > -------------------------------------------------- > > Key: HIVE-18852 > URL: https://issues.apache.org/jira/browse/HIVE-18852 > Project: Hive > Issue Type: Bug > Components: Metastore > Affects Versions: 2.4.0 > Reporter: Dan Burkert > Assignee: Andrew Sherman > Priority: Major > Attachments: HIVE-18852.1.patch > > > The metastore's validation error message when attempting to rename a table to > a non-existent database is wrong. For instance, attempting to alter table > 'db.table' to 'non_existent_database.table' results in the Thrift error: > {{TException - service has thrown: InvalidOperationException(message=Unable > to change partition or table. Database db does not exist Check metastore logs > for detailed stack.non_existent_database)}} > I believe the offending line of code is > [here|https://github.com/apache/hive/blob/branch-2/metastore/src/java/org/apache/hadoop/hive/metastore/HiveAlterHandler.java?utf8=%E2%9C%93#L331-L333], > notice that {{dbname}} is used in the message, not {{newDbName}}. I don't > know if switching that would cause the case of a non-existing {{dbname}} case > to regress, though. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
