---------------------------------------
I believe this bug describes the same issue as ACCUMULO-225, but in a more
general way. If you agree, feel free to close ACCUMULO-225.
> client code for TableConfiguration has problems
> -----------------------------------------------

> Key: ACCUMULO-240
> URL: https://issues.apache.org/jira/browse/ACCUMULO-240
> Project: Accumulo
> Issue Type: Bug
> Components: client
> Affects Versions: 1.3.5
> Reporter: Adam Fuchs
> Assignee: Adam Fuchs
>
> There are a number of problems with accessing TableConfiguration object from
> client code, the first being that TableOperationImpl uses code that relies on
> a hidden HDFSZooInstance in client configuration. If the client is not
> running with access to the HDFS Accumulo directory, or if the HDFS setup on
> the client differs from the Accumulo instance, then this call will fail:
> {noformat}
> Exception in thread "main" java.lang.ExceptionInInitializerError
> Caused by:
> org.apache.accumulo.core.client.impl.HdfsZooInstance$AccumuloNotInitializedException:
> Accumulo not initialized, there is no instance id at /accumulo/instance_id
> at
> org.apache.accumulo.core.client.impl.HdfsZooInstance._getInstanceID(HdfsZooInstance.java:136)
> at
> org.apache.accumulo.core.client.impl.HdfsZooInstance.getInstanceID(HdfsZooInstance.java:123)

> at
> org.apache.accumulo.core.client.admin.TableOperationsImpl.setLocalityGroups(TableOperationsImpl.java:583)
> {noformat}
> Another problem is that the ZooConfiguration object uses static instance
> information, negating the possibility of using multiple instances in the same
> JVM.
