Subject Re: [jira] [Resolved] (GIRAPH-583) Problem with authentication on Hadoop 0.23

Sorry about the delay. You need to change the names to something
test-specific for all "_bspZookeeper" type folders (one for ZK znodes and
one for ZKManager to use if I rememebr right, see InternalVertexRunner) and
then a port for your local ZK to use. The issue is that during tests,
multiple local ZK's can exist at once (during any integration tests that
execute concurrently) and in that case they clean up (erase) the 2nd one to
finish's data from the temp dirs if they are the same. The ZK's get
similarly confused.

So it breaks down like this: Giraph's local ZK by default uses 22181. The
IVR uses 22182. The YARN Miniclustwer from giraph 13 is using 22183. It
might be smart to take a look at factoring all integration tests that
requrie ZK into one test that can start just one ZK for all, and one common
Configuration (with the zkLIst set)? But the YARN stuff has to
conditionally compile and I would need to munge those tests into our normal

Anyway, hope that helps.
