for data transfer. (eli)
HDFS-3055. Implement recovery mode (Colin Patrick McCabe via todd)
HADOOP-8209. Add option to relax build-version check for branch-1. (eli)
HDFS-3518. Add a utility method DistributedFileSystem.isHealthy(uri) for
checking if the given HDFS is healthy. (szetszwo)
HADOOP-7823. Port HADOOP-4012 providing split support for bzip2 compressed
files to branch-1. (Andrew Purtell via cdouglas)
HDFS-3703. Datanodes are marked stale if heartbeat is not received in
configured timeout and are selected as the last location to read from.
(Jing Zhao via szetszwo)
MAPREDUCE-4328. Add a JobTracker safemode to allow it to be resilient to
NameNode failures. The safemode can be entered either automatically via
the configurable background thread to monitor the NameNode or by the
admin. In the safemode the JobTracker doesn't schedule new tasks, marks
all failed tasks as KILLED for future retries and doesn't accept new job
submissions. (acmurthy)
