Subject [jira] Commented: (HIVE-1629) Patch to fix hashCode method in DoubleWritable class
Date Mon, 13 Sep 2010 06:18:34 GMT

Ning Zhang commented on HIVE-1629:
----------------------------------

Good question John. I think this patch doesn't affect bucketing, which is implemented using
ObjectInspectorUtils.hashCode(). Actually the hash function used there for Double is the same
as the one provided in this patch. But I'll double check with Zheng/Namit tomorrow.
