Better error message in CLI on invalid column name
--------------------------------------------------
Key: HIVE-2256
URL: https://issues.apache.org/jira/browse/HIVE-2256
Project: Hive
Issue Type: Improvement
Components: CLI, Query Processor
Reporter: Sohan Jain
In the CLI, if a user inputs an incorrect column name, we currently just print
the bad column name in the query. Typically, the user needs to "describe" the
table to figure out the correct column.
This patch prints out a list of valid column and partition names in the table
when a user inputs an incorrect column name.
e.g.,
{{Error in semantic analysis: Invalid table alias or column reference
'col_does_not_exist' (possible column names are: col1, col2)}}
