Hi, Attaching a screenshot of bytes/sec from Ganglia
As you can see, the graph in RED color belongs to the third replica, for which the bytes/sec is around 10 times lower than its 2 peers (in Green and Blue) Earlier, I was thinking that it could be related to that 1 system only, but when I created a new topic with 1 partition and 3 replicas, I see similar graph on the other set of machines. I'm not sure what parameter could be causing this. Any pointers are appreciated Thanks, Prabhjot On Mon, Sep 21, 2015 at 1:20 PM, Prabhjot Bharaj <prabhbha...@gmail.com> wrote: > Hello Folks, > > Request your expertise on this > > Thanks, > Prabhjot > > On Fri, Sep 18, 2015 at 6:18 PM, Prabhjot Bharaj <prabhbha...@gmail.com> > wrote: > >> Hi, >> >> I've noticed that 1 follower replica node out of my kafka cluster catches >> up to the data form the leader pretty slowly. >> My topic has just 1 partition with 3 replicas.
