I didn't start hdfs. Standalone means local mode, not pseudo
distributed or fully distributed. I just modify the hbase-site.xml
file as following:
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///tmp/hbase-${user.name} /hbase</value>
</property>
</configuration>
then I could start hbase and interact with it. I followed the
instruction from http://hbase.apache.org/book/quickstart.html
