I have a problem about change HDFS address

[Lu Qin]

I have a accumulo 1.7.1 work with a old HDFS 2.6. Now I have a new HDFS 2.6,and change the accumulo volume to the new. I have use distcp move the data from old HDFS to the new HDFS.And start the accumulo up. Now the ‘Accumulo Overview' shows the Tables is 0 and Tablets is 0 with red background, but In  'Table Status’ I can see all tables I have. I use bin/accumulo shell and tables command,it also show all tables,but I can not scan anyone. How can I resolve it?Thanks
