m1a2st opened a new pull request, #20319:
URL: https://github.com/apache/kafka/pull/20319
The ReassignPartitionsCommand shows the topic replicas on each broker. When
using the --generate command, it returns the current partition replica
assignment. However, the log directory for each current replica is always shown
as any. This makes it impossible for users to determine which specific log
directory is being used by each replica. Therefore, we should fix this behavior.
```
Current partition replica assignment
{"version":1,"partitions":[{"topic":"test1","partition":0,"replicas":[4,2],"log_dirs":["any","any"]},{"topic":"test1","partition":1,"replicas":[2,3],"log_dirs":["any","any"]},{"topic":"test1","partition":2,"replicas":[3,4],"log_dirs":["any","any"]},{"topic":"test1","partition":3,"replicas":[2,4],"log_dirs":["any","any"]},{"topic":"test1","partition":4,"replicas":[4,3],"log_dirs":["any","any"]},{"topic":"test1","partition":5,"replicas":[3,2],"log_dirs":["any","any"]},{"topic":"test2","partition":0,"replicas":[4,2],"log_dirs":["any","any"]},{"topic":"test2","partition":1,"replicas":[2,3],"log_dirs":["any","any"]},{"topic":"test2","partition":2,"replicas":[3,4],"log_dirs":["any","any"]}]}
