Ashutosh Chauhan reopened HIVE-3750:
------------------------------------
This is making quite a few test case in TestParse and elsewhere to fail,
because golden files were not updated corresponding to maxStatsKeyPrefixLength
config which is now showing up in the outputs.
Please run all tests and update golden file (assuming they need to be updated).
> 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

>
>
> 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.
