Simon,
Can you reproduce this in plain-jane Java code? I don't know enough
about spark/scala, much less what Geomesa is actually do, to know what
the issue is.
Also, which token are you referring to: A KerberosToken or a
DelegationToken? Either of them should be usable as many times as you'd
like (given the underlying credentials are still available for KT or the
DT token hasn't yet expired).

Folks,
I am working on geomesa+accumulo+spark integration. For some reason, I
found that the same token cannot be used to authenticate twice.
The workflow is that geomesa would try to create a hadoop rdd, during
which it tries to create an AccumuloDataStore:
https://github.com/locationtech/geomesa/blob/master/geomesa-compute/src/main/scala/org/locationtech/geomesa/compute/spark/GeoMesaSpark.scala#L81
During this process, a ZooKeeperInstance is created:
https://github.com/locationtech/geomesa/blob/rc7_a1.7_h2.5/geomesa-core/src/main/scala/org/locationtech/geomesa/core/data/AccumuloDataStoreFactory.scala#L177
I modified geomesa such that it would use kerberos to authenticate
here. This step works fine.
But next, geomesa calls ConfigurationBase.setConnectorInfo:
https://github.com/locationtech/geomesa/blob/rc7_a1.7_h2.5/geomesa-compute/src/main/scala/org/locationtech/geomesa/compute/spark/GeoMesaSpark.scala#L69
This is using the same token and the same zookeeper URI, for some
reason it is stuck on spark-shell, and the following is outputted on
tserver side:

Any idea why?
