--------------------------------------

discussed with manoj offline , thanks [~manojg] for letting me to take up the jira

thanks [~tasanuma] for comments
{quote}but does it need to change listOpenFiles API? I'm a bit worried about one more deprecated listOpenFiles API
{quote}
we are adding an additional field to the return value of an existing API , so i dont think we need to deprecate a API

attached patch , please review

> HDFS-11847 has introduced a new option to {{-blockingDecommission}} to an existing command 
> {{dfsadmin -listOpenFiles}}. But the reporting done by the command doesn't differentiate the files based on the type (like blocking decommission). In order to change the reporting style, the proto format used for the base command has to be updated to carry additional fields and better be done in a new jira outside of HDFS-11847. This jira is to track the end-to-end enhancements needed for dfsadmin -listOpenFiles console output.
