Hi Muhammad,
I am new to Hbase myself, but I think I can help.
The default data storage location for Hbase is in your /tmp directory, which is
emptied by default on every reboot. Examine the conf/hbase-default.xml file for
the "hbase.rootdir" property syntax, then over-ride the default in your
hbase-site.xml file. You could, for instance set the following:
<property>
<name>hbase.rootdir</name>
<value>file:///var/hbase-data</value>
</property>
This would store your data in a directory that persists reboots.
The command to view all rows in a table from the shell is "scan 'myTable'".
Obviously, without the double quotes, and replace myTable with your own table
name.
