> At present the outputs of {{listVolume}}, {{listBucket}} and {{listKey}} are hard to
parse, for example following call
> {code}
> ./bin/hdfs oz -listVolume http://localhost:9864 -user wwei
> {code}
> lists all volumes in my cluster and it returns
> {noformat}
> {
>     "version" : 0,
>     "md5hash" : null,
>     "createdOn" : "Mon, 04 Sep 2017 03:25:22 GMT",
>     "modifiedOn" : "Mon, 04 Sep 2017 03:25:22 GMT",
>     "size" : 10240,
>     "keyName" : "key-0-22381",
>     "dataFileName" : null
>   }

>     "md5hash" : null,
>     "createdOn" : "Mon, 04 Sep 2017 03:25:22 GMT",

> this is not a valid JSON format output hence it is hard to parse in clients' script for
further interactions. Propose to reformat them to valid JSON data.
