I am not sure if the tables could be recovered seamle= ssly, the tables are stored in undelying hdfs.
I was thinking= of using http://accumulo.apache.org/1.6/examples/bulkIngest.html to recover t= he tables, the better would be if we could update the zookeeper data pointi= ng to the existing hdfs table data.
I don't have more information about it as of now, we need so= meone else to help us here.

You're right, I deleted the zk nodes and now Accumulo co= mplains nonode error.

Can I recover the tables for a new instance?

Deletion from the zookeeper should be done using the rmr /a= ccumulo command, you will have to use zkCli.sh to use zookeeper client. I h= ave been doing this sometime back, have not used it recently.
I would not recommend to delete the information in zookeeper unless t= here is not other option, you may loose the data IMO.

So how can I delete /accumulo in Zookeeper?

Or is there a way to rename instance_id?
