Hi there, KIP-113 added a new, optional filed to the input JSON file of kafka-reassign-partitions:
{ "version" : int, "partitions" : [ { "topic" : str, "partition" : int, "replicas" : [int], "log_dirs" : [str] <-- NEW. A log directory can be either "any", or a valid absolute path that begins with '/'. This is an optional filed. It is treated as an array of "any" if this field is not explicitly specified in the json file. }, ... ] } {code} KIP-113 says: This KIP is a pure addition. So there is no backward compatibility concern. Is it intentional that "version" remained 1? Regards, Attila
