    Description

      During clustering testing, sometimes the following warning happens:

      2014-11-18 11:29:38,365 | WARN | ult-dispatcher-2 | InMemoryDOMDataStore | 225 - org.opendaylight.controller.sal-inmemory-datastore - 1.2.0.SNAPSHOT | Store Tx: member-1-shard-topology-operational-0 Data Precondition failed for /(urn:TBD:params:xml:ns:yang:network-topology?revision=2013-10-21)network-topology.

      leading to error and missing BGP topology:

      2014-11-18 11:29:38,397 | ERROR | CommitFutures-0 | AbstractTopologyBuilder

      failed in transaction DOM-CHAIN-1-0
      TransactionCommitFailedException

      {message=Data did not pass validation., errorList=[R pcError [message=Data did not pass validation., severity=ERROR, errorType=APPLICATIO N, tag=operation-failed, applicationTag=null, info=null, cause=org.opendaylight.yang tools.yang.data.api.schema.tree.ModifiedNodeDoesNotExistException: Node /(urn:TBD:pa rams:xml:ns:yang:network-topology?revision=2013-10-21)network-topology does not exis t. Cannot apply modification to its children.]]}

      Notably, this error has never happened when PCEP component starts quickly enough; that may be why this bug was not visible before clustering.
      Possibly, the fix could be just to add 'true' as fourth argument, at the end of line 82 of AbstractTopologyBuilder.java
