Data Processing fails to start

Data Processing may be unable to start on production clusters that have been upgraded more than once.

If this occurs, you'll receive an error similar to the following:

[Upgrader] Switch soft link Success
[Upgrader] Starting BDD cluster...
[2015/10/08 01:07:45 -0400] [Admin Server] Starting BDD components...
[2015/10/08 01:13:17 -0400] [web009.us.example.com] Starting Dgraph.......Success!
[2015/10/08 01:13:22 -0400] [web009.us.example.com] Starting Dgraph HDFS Agent.......Success!

[2015/10/08 01:16:30 -0400] [web009.us.example.com] Starting Data Processing.......Fail!

To fix this issue, edit the following properties in edp.properties on all Managed Servers and Dgraph nodes:

oltHome=/opt/bdd/edp-<version>/olt
bddHadoopFatJar=/localdisk/Oracle/Middleware/BDD-<version>/common/hadoop/lib/bddHadoopFatJar.jar
edpJarDir=/opt/bdd/edp-<version>/lib

where <version> is the version of BDD you upgraded to, as defined by BDD_VERSION in bdd.conf.
