Subject Helix Errors on Startup
Date Wed, 29 Apr 2015 12:53:17 GMT
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
