Davies Liu created HIVE-12833: --------------------------------- Summary: GROUPING__ID is wrong Key: HIVE-12833 URL: https://issues.apache.org/jira/browse/HIVE-12833 Project: Hive Issue Type: Bug Reporter: Davies Liu
https://cwiki.apache.org/confluence/display/Hive/Enhanced+Aggregation,+Cube,+Grouping+and+Rollup Grouping__ID function This function returns a bitvector corresponding to whether each column is present or not. For each column, a value of "1" is produced for a row in the result set if that column has been aggregated in that row, otherwise the value is "0". This can be used to differentiate when there are nulls in the data. This does not match the example blow, in the first row, both key and value are aggregated, so GROUPING__ID should be 3 not, 0. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
