-----------------------------------
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.
