Subject Re: regionserver died when using Put to insert data
Date Tue, 13 Aug 2013 15:24:34 GMT
Hi Jia,

How is you HDFS running?

"Caused by: org.apache.hadoop.ipc.
RemoteException(java.io.IOException): File
/apps/hbase/data/lbc_zte_1_imei_index/4469e6b0500bf3f5ed0ac1247d249537/.tmp/e7bb489662344b26bc6de1e72c122eec
could only be replicated to 0 nodes instead of minReplication (=1).  There
are 3 datanode(s) running and no node(s) are excluded in this operation.
"

Sound like there is some issues on the datanode. Have you checked its logs?
