> StreamingTombstoneHistogramBuilder.DataHolder does not merge bins correctly
> on overflow
> ---------------------------------------------------------------------------------------
>
> Key: CASSANDRA-19381
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19381
> Project: Cassandra
> Issue Type: Bug
> Components: Local/SSTable
> Reporter: Ariel Weisberg
> Assignee: Ariel Weisberg
> Priority: Normal
> Fix For: 5.0, 5.1
>
>
> The algorithm tries to merge the two nearest points in the histogram and
> create a new point that is in between the two merged points based on the
> weight of each point. This can overflow long arithmetic with the code that is
> currently there and the work around is pick one of the points and just put
> it there.
> This can be worked around by changing the midpoint calculation to not
> overflow.
