On each node you can configure how much memory is available for containers
to run.
On the other hand, for each application you can configure how large
config.addResource(new
Path(/usr/local/hadoop-2.6.0/etc/hadoop/core-site.xml));
the path is org.apache.hadoop.fs.Path, so the resource should be in hdfs,
do you have the resource in hdfs?
can you try the API
config.addResource(InputStream in)

If the cluster have enough resource, then more than one job will run at the

I don't think it nessary to run the command with daemon in that client, and
hdfs is not a daemon for hadoop。

This is a non-sense ; you have to tell us under which conditions you want
to find a bottleneck.
yes, you can do this in java, if these conditions are satisfied
1. your client is in the same network with the hadoop cluster
2. add the hadoop configuration to your java classpath, then the jvm
will load the hadoop configuration
but the suggesttiong way is
hadoop jar

thank you for explanation. I have googled the feature, and hortonworks

This feature is a technical preview and considered under development. Do

can we use it in production env?

Do you mean you want to execute a job in the remote cluster which don't
contain you node?
If you copy the configure of RM to your own computer, and this computer
will be taken as the hadoop client. Then you can execute the job through
'hadoop jar', the job will be executed on remote cluster
