Kevin Wilfong created HIVE-3750: ----------------------------------- Summary: JDBCStatsPublisher fails when ID length exceeds length of ID column Key: HIVE-3750 URL: https://issues.apache.org/jira/browse/HIVE-3750 Project: Hive Issue Type: Bug Components: Statistics Affects Versions: 0.11 Reporter: Kevin Wilfong Assignee: Kevin Wilfong
When the length of the ID field passed to JDBCStatsPublisher exceeds the length of the column in the table (currently 255 characters) stats collection fails. This causes the entire query to fail when hive.stats.reliable is set to true. One way to prevent this would be to calculate a deterministic, very low collision hash of the ID prefix used for aggregation and use that when the length of the ID is too long. -- This message is automatically generated by JIRA.
