Subject Re: how to access configuration properties on a remote Hadoop cluster
Date Wed, 09 Jul 2014 20:02:46 GMT
Instead of <Resource-Manager-WebApp-Address>/conf, If you have application
id and job id, you can query the Resource Manager for the configuration of
this particular application. You can use HTTP and Java API for that.
