Got to know from the dev team that they have modified the column definition. We ran the MSCK repair table and we are able to run the select distinct query.  Vertex errors may not relate to memory issues. Hope this helps the community.  ... View more

@Shahrukh_shaikh - We are getting the below error when we are running the select distinct on column where it has all NULL values.  Does that mean that we should not be running distinct on such columns.  [Cloudera][Hardy] (35) Error from server: error code: '2' error message: 'Error while compiling statement: FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.tez.TezTask.
