Eric Hanson created HIVE-4472:
---------------------------------
Summary: OR Filter logic can lose an array, and always takes time
O(DEFAULT_BATCH_SIZE)
Key: HIVE-4472
URL: https://issues.apache.org/jira/browse/HIVE-4472
Project: Hive
Issue Type: Sub-task
Reporter: Eric Hanson
Assignee: Jitendra Nath Pandey
The issue is in file FilterExprOrExpr.java
I posted a review for you at
https://reviews.apache.org/r/10752/
I think there is a bug related to sharing of an array of integers. Also, one
algorithm step takes O(DEFAULT_BATCH_SIZE) time always. If
n<<DEFAULT_BATCH_SIZE then this is a performance issue.
