------------------------------------

Hi Jimmy, I tried to reproduce with the following commands, but I haven't seen anything wrong.
 Is it possible to reproduce with the command line?  I'm also not sure what to look for in
the itbll.Verify m/r output.  Any tips to reproduce?

{code}
truncate 'IntegrationTestBigLinkedList'

alter 'IntegrationTestBigLinkedList', {DATA_BLOCK_ENCODING=>'PREFIX_TREE'}

bin/hbase org.apache.hadoop.hbase.test.IntegrationTestBigLinkedList Generator 1 25000000 /home/mcorgan/junk/itbll2/generate

bin/hbase org.apache.hadoop.hbase.mapreduce.RowCounter 'IntegrationTestBigLinkedList'

major_compact 'IntegrationTestBigLinkedList'

bin/hbase org.apache.hadoop.hbase.mapreduce.RowCounter 'IntegrationTestBigLinkedList'

bin/hbase org.apache.hadoop.hbase.test.IntegrationTestBigLinkedList Verify /home/mcorgan/junk/itbll2/verify

alter 'IntegrationTestBigLinkedList', {DATA_BLOCK_ENCODING=>'NONE'}

major_compact 'IntegrationTestBigLinkedList'

bin/hbase org.apache.hadoop.hbase.mapreduce.RowCounter 'IntegrationTestBigLinkedList'

bin/hbase org.apache.hadoop.hbase.test.IntegrationTestBigLinkedList Verify /home/mcorgan/junk/itbll2/verify2

> ITBLL starts with encoding NONE. Online encoding change will try other encoding. However,
if it starts with encoding PREFIX_TREE, the test fails, even with online encoding change disabled.
