Andrew Purtell updated HBASE-1500:
----------------------------------
Attachment: test.log.gz
test.rb
To reproduce, run the attached script using the latest trunk.
{{./bin/hbase shell test.rb}}
Wait for the split to finish. Then, try a count:
{{./bin/hbase shell}}
{{hbase> count 'test'}}
{code}
count 'test'

Attached also is the master+regionserver log at DEBUG level from the test.
