Yiqun Lin commented on HDFS-15410:
----------------------------------

[~LiJinglun], one minor comment: can you add more description for the setting 
hdfs.fedbalance.procedure.scheduler.journal.uri and 
hdfs.fedbalance.procedure.work.thread.num?

For example, we can add part of some definition:
 hdfs.fedbalance.procedure.scheduler.journal.uri : The uri of the journal, the 
journal file is used for handling the job persistence and recover.
 hdfs.fedbalance.procedure.work.thread.num: The worker threads number of the 
BalanceProcedureScheduler. BalanceProcedureScheduler is responsible for 
scheduling a balance job, including submit, run, delay and recover.


 Also please update above new description in FederationBalance.md configuration 
options section that tracked in HDFS-15374. Thanks.
