Description

I found that  FileIoErrors metric will increase in BlockSender.sendPacket(),when use fileIoProvider.transferToSocketFully().But in https://issues.apache.org/jira/browse/HDFS-2054 the Exception has been ignore like "Broken pipe" and "Connection reset" .

So should do a filter when fileIoProvider increase FileIoErrors count ?
