WARN balancer.Balancer: Error moving block - Premature EOF: no length prefix available

WARN balancer.Balancer: Error moving block - Premature EOF: no length prefix available

New Contributor

I'm running a balancer and am getting intermittent WARN messages - should I be worried?

 

14/05/09 12:40:00 WARN balancer.Balancer: Error moving block 13025281412796715 from 192.168.*******:50010 to 192.168.*******:50010 through 192.168.******:50010: block move is failed: opReplaceBlock BP-29508606-192.168.*********-1376997635216:blk_13025281412796715_1952548 received exception java.io.EOFException: Premature EOF: no length prefix available

 

Thanks

Hi Yas,

 

According to this thread:

https://groups.google.com/forum/#!topic/nosql-databases/zGYnu24-JX8

 

It may help to run your os-level fsck. Seems like there may be some corruption on your regular, non-hadoop file system.

 

Thanks,

Darren
