Walter Su commented on HDFS-8762:
---------------------------------

Thanks [~libo-intel] for reporting this. I just think 001 patch is not a good 
idea. Please take a look at StripedDataStreamer#toString(). We only need to 
change 
{code}
LOG.level(message);
{code}
to
{code}
LOG.level(message + this);
{code}

> Erasure Coding: the log of each streamer should show its index

> The log in {{DataStreamer}} doesn't show which streamer it's generated from. 
> In order to make log information more convenient for debugging, each log 
> should include the index of the streamer it's generated from.
