> 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
> Attachments: HIVE-3750.1.patch.txt
>
>
> 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.
