(was: [~huxi_2b] [~junrao] Will this task be in progress someday or maybe there is some alternative how to automatically distribute partitions on disks according to partition size and not only count when multiple data log dirs are used?)

> Currently, log manager chooses a directory configured in `log.dirs` by calculating the number partitions in each directory and then choosing the one with the fewest partitions. But in some real production scenarios where data volumes of partitions are not even, some disks nearly become full whereas the others have a lot of spaces which lead to a poor data distribution.
> We should offer a new strategy to users to have log manager honor the real disk free spaces and choose the directory with the most disk space. Maybe a new broker configuration parameter is needed, `log.directory.strategy` for instance. A new KIP is created to track this issue: https://cwiki.apache.org/confluence/display/KAFKA/KIP-178%3A+Size-based+log+directory+selection+strategy
> Does it make sense?
