Hi, FYI, I created a set of jira in HDFS, related to HBase MTTR or recovery alone.
HDFS-3706 :Add the possibility to mark a node as 'low priority' for reads in the DFSClient HDFS-3705: Add the possibility to mark a node as 'low priority' for writes in the DFSClient HDFS-3704: In the DFSClient, Add the node to the dead list when the ipc.Client call fails HDFS-3703: Decrease the datanode failure detection time HDFS-3702: Add an option for NOT writing the blocks locally if there is a datanode on the same box as the client HDFS-3701: HDFS may miss the final block when reading a file opened for writing if one of the datanode is dead N.
