Vimal,
Maybe you should try running the test case for HBASE-9410 (with some modifications) and report
back.
This way Lars/committers/contributors can work on this bug with confirmation.


The test case makes a coprocessor call (which does nothing) on a table with regions in all
the region servers.
Feel free to send me any email in this regards. 
 
Regards,
- kiru

Hi.
I am still getting these warnings in region server logs.
I am still using hbase 0.94.7.
Is there any impact of these warning messages ?
