copying Accumulo tables to another cluster

[Jayesh Patel <jp...@keywcorp.com>]

I'm hoping to copy the data from my Accumulo cluster to a new cluster using
the Hadoop distcp command and run Accumulo on the new cluster using the same
data.

 

Is this feasible?  

 

First time I tried this, I copied the whole /accumulo hdfs folder and the
zookeeper in the new cluster kept complaining about not finding the nodes
for various processes trying to get their locks.

 

Should I instead just copy the tables and wal folders?

 

Thank you,
Jayesh

It will not work to copy the raw HDFS directory.

Please use the importtable and exporttable Accumulo shell commands.
