[jira] [Created] (HBASE-4356) Wide rows can cause OOME when
compacting
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.
