--------------------------------------
Right. It helps for debugging. ZooKeeper supports [4 letter words commands |
http://zookeeper.apache.org/doc/r3.1.2/zookeeperAdmin.html#sc_zkCommands] like
ruok, stat. We can hook with
avro-client options:
--ruok
> Consider adding areYouOK() RPC calls to Avro & Thrift RPC mechanisms

> Currently it's not simple to see if an Avro RPC service is alive on a port
> from an external service (think hardware load balancer or health check
> daemon). If we added RPC calls for areYouOK() or something like that it would
> help with these use cases.
