While the context of
http://accumulo.apache.org/1.7/accumulo_user_manual#_migrating_accumulo_from_non_ha_namenode_to_ha_namenode
isn't quite the same as you, the steps of handling the address for a
namenode changing is the same (more practical steps on how to configure
instance.volumes.replacements).

to map your metadata from the old location to the new one.

Accumulo stores data in HDFS and Zookeeper. Are you using
new zookeeper servers? If so, did you copy zookeepers data?

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
