Hi Michael, What table is affected? Are there relevant entries for that table in the HMaster log? Are there relevant entries in the regionserver logs for either META or the affected table?
You can use the HMaster UI running on port 60010 to learn which regionserver is hosting META: http://<hmaster>:60010/ then click on '.META.' listed under "Catalog Tables".
