Subject [jira] [Updated] (HIVE-2909) SHOW COLUMNS table_name; to provide a comma-delimited list of columns.

Phabricator updated HIVE-2909:
------------------------------

    Attachment: HIVE-2909.D2595.1.patch

dikanggu requested code review of "HIVE-2909 [jira] SHOW COLUMNS table_name; to provide a
comma-delimited list of columns.".
Reviewers: JIRA

  add the show columns in hive cli

  Due to the way that SELECT * and partitioning works, it is frequently obnoxious to insert
data into tables of the same schema.

  This could be fixed in a number of ways, all murky; this feature request reduces the obnoxicity
of the current situation.

  SHOW COLUMNS foo;
  OK
  bar, baz, tball, ds

  ...then I could just copy the first three and not the last.

TEST PLAN
  unit test, show_columns.q
