>            Reporter: Lars George
>            Assignee: Lars George

> I have various regions that report the following error:
> ERROR org.apache.hadoop.hbase.regionserver.CompactSplitThread: Compaction failed for
region storedata,10edd32a3fa217e,1247877829376
> java.lang.RuntimeException: ScanWildcardColumnTracker.checkColumn ran into a column actually
smaller than the previous column!
>       at org.apache.hadoop.hbase.regionserver.ScanWildcardColumnTracker.checkColumn(ScanWildcardColumnTracker.java:89)
>       at org.apache.hadoop.hbase.regionserver.ScanQueryMatcher.match(ScanQueryMatcher.java:162)
> They are most likely remnants of HBASE-1715 and its linked issues?
> Add more features to HFile.main() to be able to figure the files that are broken (as
the error above only reports the region) and how.
