Hi Tho,
As fat as I know, with version 0.2.0 there must be either no hbase dir,
of an already initialized one.
Good luck

Hi All,
I cannot start HBase master when setting root directory of HBase is a
folder in HDFS.
Hadoop version: 0.17.1
HBase version: 0.2.0
My hbase-site.xml configuration file
<configuration>
<property>
<name>hbase.master</name>
<value>192.168.1.5:60000</value>
</property>
<property>
<name>hbase.rootdir</name>
<value>hdfs://192.168.1.5:50000/hbase</value>
</property>
</configuration>
HDFS is already formated. The HDFS server started OK. The hbase folder
is existed in hdfs://192.168.1.5:50000.
The hadoop-site.xml configuration file is already in $HBASE_HOME/conf
folder.
But I cannot start HBase master. Please see the log file.

I don't know why system tells me have to migrate the file system. I
know that, hbase-0.2.0 is available with hadoop-0.17.1.
Please help me.
Best regards,
Tho Pham
