> * The client open this file and seeks to the offset of 1024KB to read data.
> * Call DFSInputStream#getBlockReader method connect to the datanode, because
> at this time the datanode access token is invalid will throw
> InvalidBlockTokenException., and call DFSInputStream#fetchBlockAt will throw
> java.lang.IndexOutOfBoundsException.
