can't start hbase after crash

my hbase(phoenix) crashes when the disk is full. I killed the hbase
and hadoop related processes. But After that I can't start hbase
anymore.
I am using ubuntu 12.04 and hadoop-1.2.1 and hbase 0.98.5 with phoenix 4.1.0
The region server print error like:

I also find warns like
wal.FSHLog: HDFS pipeline error detected. Found 1 replicas but
expecting no less than 3 replicas.  Requesting close of hlog.
But my hbase cluster is pesudo cluster that all processes are running
in a single machine and the hdfs (I have set dfs.replication=1 in
hdfs-site.xml)

Re: can't start hbase after crash

Posted by James Taylor <ja...@apache.org>.
Also, probably best to move this to the HBase mailing list, as this
isn't Phoenix-specific.

Thanks,
James
