ATTACHMENT ID: 12637948
> Add protection against divide by zero in stats annotation
> ---------------------------------------------------------

> Key: HIVE-6797
> URL: https://issues.apache.org/jira/browse/HIVE-6797
> Project: Hive
> Issue Type: Sub-task
> Components: Query Processor, Statistics
> Affects Versions: 0.13.0
> Reporter: Prasanth J

> In stats annotation, the denominator computation in join operator is not
> protected for divide by zero exception. It will be an issue when NDV (count
> distinct) updated by updateStats() becomes 0. This patch adds protection in
> updateStats() method to prevent divide-by-zero in downstream operators.
