Reporter: Lee Hounshell
There is an issue with Hadoop 2.7.0 when in distributed operation the datanode
is unable to reach the yarn scheduler. In our yarn-site.xml, we have defined
this path to be:
<property>
<name>yarn.resourcemanager.scheduler.address</name>
<value>qadoop-nn001.apsalar.com:8030</value>
</property>
But when running an oozie job, the problem manifests when looking at the job
logs for the yarn container.
We see logs similar to the following showing the connection problem:

To prove the problem, we have patched the file:
hadoop-2.7.0/src/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/client/RMProxy.java
so that we now "inject" the yarn.resourcemanager.scheduler.address directly
into the configuration.
The modified code looks like this:
@Private
protected static <T> T createRMProxy(final Configuration configuration,
final Class<T> protocol, RMProxy instance) throws IOException {
YarnConfiguration conf = (configuration instanceof YarnConfiguration)
? (YarnConfiguration) configuration
: new YarnConfiguration(configuration);
LOG.info("LEE: changing the conf to include
yarn.resourcemanager.scheduler.address at 10.1.26.1");
conf.set("yarn.resourcemanager.scheduler.address", "10.1.26.1");
RetryPolicy retryPolicy = createRetryPolicy(conf);
if (HAUtil.isHAEnabled(conf)) {
RMFailoverProxyProvider<T> provider =
instance.createRMFailoverProxyProvider(conf, protocol);
return (T) RetryProxy.create(protocol, provider, retryPolicy);
} else {
InetSocketAddress rmAddress = instance.getRMAddress(conf, protocol);
LOG.info("LEE: Connecting to ResourceManager at " + rmAddress);
T proxy = RMProxy.<T>getProxy(conf, protocol, rmAddress);
return (T) RetryProxy.create(protocol, proxy, retryPolicy);
}
}
