Description

kafka-topics.sh command not honouring --disable-rack-aware property when adding partitions.

Create topic honours --disable-rack-aware property. Where as alter topic always honours default rackAwarMode(Enforced) to add partitions.

Steps:

• Start brokers.
          0 -> r1, 1 -> r1, 2 -> r2, 3 -> r2
• Create topic topic1 with 8 partitions and 2 RF. No partition should have replicas on same rack brokers. Ex: 0,1 and 2,3 replica should never be created. Create topic topic2 with 8 partitions and 2 RF with --disable-rack-aware. Partition can have replicas on same rack brokers. Ex: 0,1 and 2,3 replica if present is acceptable.
• Add 8 more partitions to topic1. No newly added partition should have replicas on same rack brokers. Ex: 0,1 and 2,3 replica should never be created.
• Add 8 more partitions to topic2 with --disable-rack-aware_._ Newly added partition can have replicas on same rack brokers. Ex: 0,1 and 2,3 replica if present is acceptable. Try repeating this step, no matter what, partitions are always rack-aware.
