> Iceberg: Count(*) fails for V2 tables with delete files.
> --------------------------------------------------------
>
> Key: HIVE-26709
> URL: https://issues.apache.org/jira/browse/HIVE-26709
> Project: Hive
> Issue Type: Bug
> Reporter: Ayush Saxena
> Assignee: Ayush Saxena
> Priority: Major
> Labels: pull-request-available
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Steps to Repro.
> * Create a v2 table
> * Add some Data
> * Delete a Row
> * Do a count(*) on the table
> *Reason:* Missing RoaringBitmap dependency, Iceberg now requires it during
> runtime for Delete files filtering
> StackTrace:
> {noformat}
