Duplicate consumer when add_job param of repli no equal the cluster node numbers

[runingriver]

ENV: cluster has three node of A,B,C
Case Step:

1. add 100 job to A, param: replicate=1, and other param with default.
   now result: A: info - registered_jobs=100,qlen=100; B:info - registered_jobs=0,qlen=0;C: same as B
2. clinet connect to C to consumer all of those jobs
   now result: A: info - registered_jobs=100,qlen=0; B:info - registered_jobs=0,qlen=0;C: same as B
   Note: the registered_jobs=100 at the time!
   And consumer client connect to A, 100 jobs duplicate send to A!
   But when A,C be connected at the same time, result is only be consumered once only
   Unreasonable it is?
