Description

"SplitTransaction: Split row is not inside region key range or is equal to startkey".

I stopped writers after realizing one region of the table was growing unbounded:

webtable,DE0CBA1D6CDFCDD6CBC1065D2C9C1CA17BDA0FAF,1291557809928.
deccb20bcbf8e634008cf093105c4fc5.
            stores=3, storefiles=10, storefileSizeMB=6753, memstoreSizeMB=2,
 storefileIndexSizeMB=2

In the regionserver log, every compaction of this region fails to split with the following message:

2010-12-05 09:04:50,156 INFO org.apache.hadoop.hbase.regionserver.SplitTransaction: 
Split row is not inside region key range or is equal to startkey: 
DE0CBA1D6CDFCDD6CBC1065D2C9C1CA17BDA0FAF

However there are many rows in the region:
