             Summary: Data loss after compaction when a row has more than Integer.MAX_VALUE columns
                 Key: HBASE-15133
                 URL: https://issues.apache.org/jira/browse/HBASE-15133
             Project: HBase
          Issue Type: Bug
          Components: Compaction
            Reporter: Toshihiro Suzuki


We have lost the data in our development environment when a row has more than Integer.MAX_VALUE columns after compaction.

I think the reason is type of StoreScanner's countPerRow is int.

https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/StoreScanner.java#L67

After changing the type to long, it seems to be fixed.
