Subject Struggling to use Zookeeper 3.4.5-1392090 for HBase 0.94.9 tests
Date Wed, 06 Nov 2013 10:53:11 GMT
Hi Zookeepers,
I'm in the process of upgrading the HBase version over in Apache Gora from
0.90.4 to 0.94.9.
For our test suite we use an embedded HBase cluster [0]. The configuration
for which can also be seen here [1].
When I attempt to initiate the HBase cluster, I get the following output
(I've removed the classpath entries for brevity).

Based on the way we run the instance and the zoo.cfg, I wonder if anyone
can point out to me what I need to do (config-wise?) to permit the
connection?

Thank you very much in advance.
Best
Lewis
