> Project: Hadoop HDFS
> Issue Type: Bug
> Components: balancer & mover
> Reporter: Tsz Wo Nicholas Sze

> This is a performance bug – Balancer may pair a source datanode and a target
> datanode with different storage types. Fortunately, it will fail schedule any
> blocks in such pair since it will find out that the storage types are not
> matched later on.
> The bug won't lead to incorrect results.
