I'm attempting to deploy a cluster entity through an ambari-managed falcon. This is a clean install from 1.6.1.
When submitting the cluster definition, I get the following message: $ sudo -u admin falcon entity -submit -file cluster.xml -type cluster Error: Invalid Execute server or port: <hostname redacted>:8050 Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses. mapreduce.framework.name is set yarn (per ambari deployment defaults). My configuration line looks like this: <interface type="execute" endpoint="<hostname redacted>:8050" version="2.4.0" /> Enabling debugging in the hadoop packages in the log4j.xml shows that the connection is being considered but not established. 2014-08-07 15:23:03,513 DEBUG - [1141105573@qtp-216944274-0:admin:POST//entities/submit/cluster a1b37e55-34fb-48f3-830d-e8e736f79c75] ~ Trying ClientProtocolProvider : org.apache.hadoop.mapred.YarnClientProtocolProvider (Cluster:90) at org.apache.hadoop.mapred.YarnClientProtocolProvider.create(YarnClientProtocolProvider.java:34) at org.apache.hadoop.mapred.YarnClientProtocolProvider.create(YarnClientProtocolProvider.java:34) at org.apache.hadoop.mapred.YarnClientProtocolProvider.create(YarnClientProtocolProvider.java:34) 2014-08-07 15:23:03,971 INFO - [1141105573@qtp-216944274-0:admin:POST//entities/submit/cluster a1b37e55-34fb-48f3-830d-e8e736f79c75] ~ Failed to use org.apache.hadoop.mapred.YarnClientProtocolProvider due to error: null (Cluster:113) Any ideas of what could be wrong are appreciated. I am able to launch other yarn jobs on this cluster successfully via Hive.
