Andy,
It seems to be there is version mismatch. What Hadoop and HBase version
you are using?
Thanks & Regards

Subject: Re: problem in configuring hbase with hdfs
Xudong Du,
While I appreciate answering HBase questions, I prefer to do that on
the HBase users mailing list for everyone's benefit.
Your problem seems to be that the HDFS Namenode is running but you
don't have any datanode, so the file was created in the namespace but
you can't read it. Make sure your HDFS is ok before running HBase.
BTW, that's the same resolution I gave later in the thread you pasted
in your mail (March 18).
I hope this solves your problem,
J-D
