command line tool for checking topic partition -> bookie ledger mapping in Pulsar?

Is there a command line tool that can tell the mapping between Pulsar topic partition and bookie ledgers? The data stored in zookeeper is in binary and is not readable directly. 

 get /devpulsar01/managedledgers/logging/benchmark/persistent/test-partition-5
