Guozhang Wang updated KAFKA-1796:
---------------------------------
Description: We need to sanity check the input json has the valid values
before triggering the admin process. For example, we have seen a scenario where
the json input for partition reassignment tools have partition replica info as
{broker-1, broker-1, broker-2} and it is still accepted in ZK and eventually
lead to under replicated count, etc. This is partially because we use a Map
rather than a Set reading the json input for this case; but in general we need
to make sure the input parameters like Json needs to be valid before writing
it to ZK. (was: We need to sanity check the input json has the valid values
(for example, the replica list does not have duplicate broker ids, etc) before
triggering the admin process.)
