druid 0.7.0, coordinator start fails

[Vijayant Singh]

Hi,

I'm setting up a druid 0.7.0 cluster, with following common config file:

druid.extensions.localRepository=/installations/druid-0.7.0/repo/

# Extensions

druid.extensions.coordinates=[]

# Zookeeper

druid.zk.service.host=10.28.124.84

# Metadata Storage (mysql)

druid.extensions.coordinates=["io.druid.extensions:mysql-metadata-storage:0.7.0-SNAPSHOT"]

druid.metadata.storage.type=mysql

druid.metadata.storage.connector.connectURI=jdbc\:mysql\://10.28.124.84\:3306/druid

druid.metadata.storage.connector.user=druid

druid.metadata.storage.connector.password=diurd

druid.extensions.searchCurrentClassloader=true

# Deep storage (local filesystem for examples - don't use this in production)

druid.storage.type=local

druid.storage.storage.storageDirectory=/tmp/druid/localStorage

# Query Cache (we use a simple 10mb heap-based local cache on the broker)

# Caching

druid.cache.type=memcached

druid.cache.hosts=10.28.124.88

druid.cache.expiration=2147483647

druid.cache.memcachedPrefix=d1

druid.cache.maxOperationQueueSize=1073741824

druid.cache.readBufferSize=10485760

# Indexing service discovery

druid.selectors.indexing.serviceName=overlord

# Monitoring (disabled for examples)

druid.monitoring.monitors=["com.metamx.metrics.JvmMonitor"]

# Metrics logging (disabled for examples)

druid.emitter=noop

Coordinator start fails with the following error:

Where am I going wrong?

Help is much appreciated.

I've found the issue, "0.7.0-SNAPSHOT" was the problem.
