------------------------------------
This is a sample json output. There is no extra information except for the
owner and stateEnterTime for end user in the containerInfo.
{
"state" : "OPEN",
"pipeline" : {
"containerName" : "ContainerForTesting00",
"lifeCycleState" : "OPEN",
"type" : "STAND_ALONE",
"factor" : "ONE",
"pipelineName" : null
},
"stateEnterTime" : 334864604,
"owner" : "OZONE",
"containerName" : "ContainerForTesting00"
}

I have tested the hdfs oz and corona commands and they are working fine. I have
tested put and get key for hdfs oz and ran a corona job I do not see an end
user in this case. Maybe I am missing something. Can you please point me to it?
