[GitHub] [hadoop] steveloughran commented on pull request #5117: HADOOP-18521. ABFS ReadBufferManager must not reuse in-progress buffers

   going to have to rebase this.
   
   i also intend to have prefetch threads update the input streams with
   * gauge of active prefetches
   * amount of data/duration
   measuring how much data was discarded for a stream would be interesting too, but a bit fiddlier
   
   reader thread jsut gets iostats off the stream, casts to IOStatisticsStore then uses it as a duration tracker and gauge stats source; straightforward
