Resolution: Duplicate
Dup of HBAE-3421
> Wide rows can cause OOME when compacting
> ----------------------------------------
>
> Key: HBASE-4356
> URL: https://issues.apache.org/jira/browse/HBASE-4356
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.90.4
> Reporter: Nate Putnam
>
> The scanner used for compaction doesn't limit the number of columns retrieved
> when doing a compaction. If a row exists with tens of millions of rows it can
> fill all available memory and crash the region server.
> It would be better if the scanner could page through the columns of wide rows
> when performing a compaction.
