[jira] [Created] (IMPALA-9487) SHOW and DESCRIBE statements should display EC policies

Sahil Takiar created IMPALA-9487:
------------------------------------

             Summary: SHOW and DESCRIBE statements should display EC policies
                 Key: IMPALA-9487
                 URL: https://issues.apache.org/jira/browse/IMPALA-9487
             Project: IMPALA
          Issue Type: Sub-task
            Reporter: Sahil Takiar


Since EC policies can be set per-file, the {{show files}} command should display if a file is an EC file, and what the EC policy is.

EC policies can be set on a table level directory, so it would be useful if 'describe extended [table-name]' indicated if the table had an EC policy set or not.

For partitioned tables, {{show partitions}} should list out the EC policy of each partition directory (we already do something similar for HDFS cacheing).
