Colin Patrick McCabe updated HDFS-2797:
---------------------------------------
Attachment: HDFS-2797.001.patch
HDFS-2797.001.patch
* add a test for the standby becoming active with a partial transaction logged
* add clearLimit method to PositionTrackingInputStream
* fix skip logic in EditLogFileInputStream. InputStream#skip can skip less
than the requested number of bytes. Also, it's prudent to clear any limit set
in the PositionTrackingInputStream. It's quite possible for the end of the
file to be longer than the maximum transaction length.
