Description
BlockManager#maxReplicationStreams, replicationStreamsHardLimit, blocksReplWorkMultiplier and PendingReconstructionBlocks#timeout these variables may be writen by NameNode#reconfReplicationParameters then while read by the other threads.
Thus they should be declared as volatile to make sure the "happens-before" consistency.
