> With HDFS-2074, the NameNode can read through any "in-progress" logs it finds
> during startup to determine how many transactions they have. It can then
> re-name the file from its inprogress name to its finalized name. For example,
> if it finds a file edits_10_inprogress with 3 transactions, it can rename it
> to edits_10-12 at startup. This means that other parts of the system like
> edits-log-transfer don't need to worry about in-progress logs.
