Helix Errors on Startup

Hi,

We always get the following errors on startup.. (#1 looks like the leader
elector for controller... ) . Ours is a FULL_AUTO embedded controller helix
configuration.
1.org.apache.helix.manager.zk.ZkBaseDataAccessor.doCreate(ZkBaseDataAccessor.java:138)
Node already exists. path:
/streamio/STATEMODELDEFS/STORAGE_DEFAULT_SM_SCHEMATA


2.
org.apache.helix.manager.zk.CallbackHandler.invoke(CallbackHandler.java:130)

Skip processing callbacks for listener:
org.apache.helix.messaging.handling.HelixTaskExecutor@1a9f9f09, path:
/streamio/INSTANCES/datapipe11-sjc1-controller-/MESSAGES, expected types:
[CALLBACK, FINALIZE] but was INIT


3.org.apache.helix.healthcheck.ParticipantHealthReportTask.stop(ParticipantHealthReportTask.java:67)
ParticipantHealthReportTimerTask already stopped
org.apache.helix.healthcheck.ParticipantHealthReportTask in stop at line 67

Things are working after this, but want to make sure if something is amiss
(or we are doing something wrong)
Thanks
Vinoth

Hi Jason,

We are on 0.6.5. I will file a ticket for each and take a stab at it :)

Hi Jason,

I have seen #2 happen during start up even if there is no gc. I dint get a
chance to dig deeper why it happens but things work as expected.

Hi Vinoth, #2 is harmless but should not happen unless there is gc. are you
using 0.6 or 0.7?

Thanks,

Hi Vinoth,

These are warnings and can be ignored. Can you please a jira on this. We
will fix it for next release.

Thanks
