for all hive roles again, and the error seems to be gone. lets see what the
future brings.

hey everyone,
I've got supplied with a decent ten node CDH 4.4 cluster, only 7 days old,
and someone tried some HBase stuff on it. I wanted to apply my (on another
cluster working) workflow's to that cluster (consisting of HiveQL Scripts
and Oozie Workflows) but unfortunately i the following issue: When trying
to drop some select statement on any table (sample tables or tables
regarding my workflow) i get the following error stack (from beeswax and
from Hive CLI):
java.io.IOException:

I tried already setting up a new table (blank) and inserting some dummy data,
but the error keeps the same. Some connection between HDFS and Hive regarind
block information seems to be broken. Any idea how to fix this or where the
configuration is to get rid of this or what other things we should check?
Cheers
Fabian
