Solution 1:^[1]

Means you've set log.dirs to include /var/lib/kafka, but there's a data subdirectory there that doesn't match the format [topic]-[partition]. Depending on what's in the data folder, fix might include using that, or making a new one that's empty

In a production Kafka installation, you'd mount individual disks for storing Kafka data rather than store it on the OS drive under /var

Solution 2:^[2]

You should not create directory /var/lib/kafka/data. When you start kafka then kafka will create directory on path from server.properties.
