Jason Lowe commented on TEZ-3833:
---------------------------------
{{shouldRetry}} is explicitly checking for an instance of {{SocketTimeoutException}} and will
always return false if it isn't. The following code will always wrap the exception as an
{{IOException}}, defeating the entire purpose of {{shouldRetry}}:
{code}
if ((ioe instanceof InternalError) || shouldRetry(srcAttemptId, new IOException(ioe)))
{
{code}
> AM should retry map attempts if the reduce task encounters commpression related errors.
