[SPARK-16115][SQL] Change output schema to be partition for SHOW PARTITIONS
command and â¦
## What changes were proposed in this pull request?
Changes include:
1. For the SHOW PARTITIONS command, the column name in the output is
changed from 'result' to 'partition' as it is more descriptive. This is now
similar to Hive.
2. Corner case: Improve the error message when calling show partitions on a
non-existent table.
Add a check to see if table exists or not and add error message.
Without the fix:
scala> spark.sql("show partitions t1");
org.apache.spark.sql.AnalysisException: SHOW PARTITIONS is not allowed on a
table that is not partitioned: default.t1;
With the fix:
scala> spark.sql("SHOW PARTITIONS T1").show;
org.apache.spark.sql.AnalysisException: Table does not exist;
## How was this patch tested?
- Added unit tests to cover these two scenarios
- Following unit tests were run successfully: hive/test, sql/test,
catalyst/test
