> One of the parts of HDFS-1799 (Ivan suggested the larger patch be split into some smaller ones)
> This adds a {{state}} variable to FSEditLog which is used to track whether the edit log is currently writing to edits, edits.new, or not writing at all (ie closed/uninitialized). This is basically a change for added safety and convenience of assertions/preconditions.
