Key: HIVE-2301
URL: https://issues.apache.org/jira/browse/HIVE-2301
Project: Hive
Issue Type: Bug
Components: CLI
Affects Versions: 0.8.0
Reporter: Paul Yang
Priority: Minor
If an alter table is run to rename a column to the same name as a partition
column, the alter will succeed. However, subsequent operations on that table
will fail.
{code}
hive> create table tmp_pyang_test (key string) partitioned by (ds string);
OK
Time taken: 4.773 seconds
hive> alter table tmp_pyang_test replace columns (ds string);
OK
Time taken: 1.254 seconds
hive> describe tmp_pyang_test;
FAILED: Error in metadata: Partition column name ds conflicts with table
columns.
FAILED: Execution Error, return code 1 from
