Subject Re: ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 Times

Which port does your HDFS listen to? It is not 9000, right?

<name>hbase.rootdir</name>
    <value>hdfs://localhost:9000/hbase</value>

You need to fix this and make sure your HDFS is working, for example,
the following command should work for you.

hadoop fs -ls /
