Hi, yes i mean the tablets.
And i need the Key object for some implementation on Geowave. I tried as you said. But i get the Exception "org.apache.accumulo.core.client.AccumuloSecurityException: Error BAD_AUTHORIZATIONS for user root on table t1(ID:1) - The user does not have the specified authorizations assigned" I am using miniAccumuloCluster. Do you know how to set the authorization?
