Steve Loughran commented on HADOOP-12844:
-----------------------------------------
I've taken this over. It's actually simpler than this patch, as all that's
needed is the existing clause catching some socket exceptions to be expanded to
catch any IOE, and then log and retry ... this is common code which can be
shared in both read operations.
what is important is to catch and respond to EOF exceptions before the generic
IOE clause
> Recover when S3A fails on IOException in read()

> This simple patch catches IOExceptions in S3AInputStream.read(byte[] buf, int
> off, int len) and reopens the connection on the same location as it was
> before the exception.
> This is similar to the functionality introduced in S3N in
> [HADOOP-6254|https://issues.apache.org/jira/browse/HADOOP-6254], for exactly
> the same reason.
> Patch developed in cooperation with [~emres].
