Maven Test failing
Hello,
Tests are failing in core. Appears to me that connection to zookeeper is
lost. Any idea what might be going wrong?

Actually sometimes this test fails even its the sole test being run. I
discovered this seems to be a known issue on macs. The solution is
increasing the Thread.sleep time to 10000 after startup.

Hey,
that is obviously a parallel execution problem.
You can either turn that off or fix the zookeeper testcases so that their
ports don't collide with each other.

Re: Maven Test failing
Posted by Apurv Verma <da...@gmail.com>.
All zookeeper related tests are failing for me. I am using MacOSX with
java6.
12/10/09 03:00:02 ERROR sync.ZKSyncClient: Error checking zk path
/bsp/job_abc_0001/1/test
org.apache.zookeeper.KeeperException$ConnectionLossException:
KeeperErrorCode = ConnectionLoss for /bsp/job_abc_0001/1/test

at org.apache.zookeeper.ZooKeeper.exists(ZooKeeper.java:809)
at org.apache.zookeeper.ZooKeeper.exists(ZooKeeper.java:837)
Tried debugging TestZookeeper test, individually they don't fail (by a
small tweak, calling close() on peerClient and masterClient at the end of
the test), but in the mvn test they break. I think this is a zookeeper
problem? Any idea about how to solve it?
