Increasing replication factor of existing topics

["Navneet Gupta (Tech - BLR)" <na...@flipkart.com>]

Hi,

I got a method to increase replication factor of topics here
<https://kafka.apache.org/081/ops.html>

However,  I was wondering if it's possible to do it by altering some nodes
in zookeeper.

Thoughts/suggestions welcome.

The partition reassignment is started by writing a zookeeper node in the
admin tree. While it's possible to kick off the partition reassignment by
writing the zookeeper node that controls it directly, you have to be very
careful about doing this, making sure that the format is perfect and you
perform all the same checks that the command line tool does. If you're
asking if you can just change the /brokers/topics/* znodes directly, the
answer is no.

Hi Navneet,
          Any reason that you are looking to modify the zk nodes directly to increase the topic partition. If you are looking for an api to do this there is AdminUtils.addPartitions .
