Jobtracker HA and oozie

[#1]

Hello, I have a hadoop cluster with CDH 4.4.0 and HDFS HA and JobTracker HA.

I tried to lunch oozie workflow but got this:

JA006: Call From xxxx to xxxx failed on connection exception: java.net.ConnectException: Connection refused; For more details see:http://wiki.apache.org/hadoop/ConnectionRefused

I found this: https://issues.cloudera.org/browse/HUE-1631

But I don't know how to fix my problem. Where to configure oozie to work with JobTracker HA?

Hi cconnor,

thanks for the reply! We're running CDH 4.6 with CM 4.8.2 and to me it looks like that at least CM doesn't configure the logical_name property automatically yet, does it? Also I can't find a dedicated config field in CM. So I suppose the safety valve is still they way to go?

Thanks in advance!

That's right, you'll have to put the following in your Hue Service->Configuration->Hue Server->Advanced->Hue Server Configuration Safety Valve for hue_safety_valve_server.ini:

[hadoop]
[[mapred_clusters]]
[[[default]]]
jobtracker_host=cdh45-2.qa.test.com
thrift_port=9290
jobtracker_port=8021
submit_to=true
hadoop_mapred_home={{HADOOP_MR1_HOME}}
hadoop_bin={{HADOOP_BIN}}
hadoop_conf_dir={{HADOOP_CONF_DIR}}
security_enabled=true
logical_name=logicaljt
[[[jtha]]]
jobtracker_host=cdh45-1.qa.test.com
thrift_port=9290
jobtracker_port=8021
submit_to=true
hadoop_mapred_home={{HADOOP_MR1_HOME}}
hadoop_bin={{HADOOP_BIN}}
hadoop_conf_dir={{HADOOP_CONF_DIR}}
security_enabled=true
logical_name=logicaljt

Leaving off "secuirty_enabled=true" if you're not using kerberos.
