Subject FailoverProxyProvider Error on Launch
Date Fri, 03 Mar 2017 19:37:59 GMT
Hi, all – my application submits to the gateway, is accepted, but then fails with:

017-03-03 14:30:50,505 INFO org.apache.hadoop.service.AbstractService: Service com.datatorrent.stram.StreamingAppMasterService

This seems related to http://stackoverflow.com/questions/38262064/exception-while-running-spark-submit-on-hadoop-cluster-with-highavailability

But I don’t know how this applies in the current situation. Wouldn’t DT retrieve the core-site/hdfs-site
from the Hadoop path we provide when setting up the gateway?

Our cluster is now deployed as an HA cluster, which wasn’t the case the last time we ran

Any ideas on how to resolve this would be much appreciated. Thanks!
