I have the hadoop configured with
<property>
<name>dfs.data.dir</name>
<value>/mnt/hadoop/data</value>
<description>Default block replication.
The actual number of replications can be specified when the file is
created.
The default is used if replication is not specified in create time.
</description>
</property>
and my HBase has
<property>
<name>hbase.rootdir</name>
<value>hdfs://cdh1:54310/hbase</value>
<description>The directory shared by region servers.
</description>
</property>
the hdfs://cdh1:54310 is the hadoop url.
I would have expected the hbase dir , created at /mnt/hadoop/data/hbase but
it is being created at the user root. When I run MR on hadoop independent of
HBase , the data files are created at /mnt/hadoop/data/ thus proving that
hadoop independently is honoring the dfs.data.dir.
NOTE that I have the hdfs-site.xml sym linked up in [HBase_Dir]/conf though
I do not think it matters.
