title: Confusion of Hbase drop table
body: <p>In the Hbase command line,when I wanted to create one table for example table1,but couldn't success,the output was:"The table already exists".So then I drop it,but still could not success,said:"the table exist".so I was very confused,when I issued list command I couldn't find the table1,but when I list hadoop hdfs directory I could find it.
  So could you please help find the reason.
  Thanks in Advance</p>
