Dong Lin updated KAFKA-7829:
----------------------------
    Description: 
In ReassignPartitionsCommand, the --reassignment-json-file option says "...If 
absolute log directory path is specified, it is currently required that the 
replica has not already been created on that broker...". This is inaccurate 
since we support moving existing replicas to new log dirs.

In addition, the Javadoc of AdminClient.alterReplicaLogDirs(...) should show 
the API is supported by brokers with version 1.1.0 or later.

In ReassignPartitionsCommand, the --reassignment-json-file option has the 
following. This seems inaccurate since we support moving existing replicas to 
new log dirs.

If absolute log directory path is specified, it is currently required that " +
"the replica has not already been created on that broker. The replica will then 
be created in the specified log directory on the broker later


> Javadoc should show that alterReplicaLogDirs() is supported in Kafka 1.1.0 or
