> 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

> 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.
