Ishita Mandhan commented on KAFKA-3940:
---------------------------------------
If dir is changed from File to Files here
https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/log/Log.scala#L78,
several functions will not be available for the type Files and alternative
implementations will need to be created for each of those calls. Is this what
you meant or am I misunderstanding something?
> Log should check the return value of dir.mkdirs()

> In Log.loadSegments(), we call dir.mkdirs() w/o checking the return value and
> just assume the directory will exist after the call. However, if the
> directory can't be created (e.g. due to no space), we will hit
> NullPointerException in the next statement, which will be confusing.
