[jira] [Created] (HADOOP-16155) S3AInputStream read(bytes[]) to not retry on read failure: pass action up

             Summary: S3AInputStream read(bytes[]) to not retry on read failure: pass action up
                 Key: HADOOP-16155
                 URL: https://issues.apache.org/jira/browse/HADOOP-16155
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.2.0
            Reporter: Steve Loughran


The S3AInputStream reacts to read(byte[]) failure by reopening the stream, just as for the single byte read(). We shouldn't need to do that. Instead just close the stream, return 0 and let the caller decided what to do. 

why so? 
# its in the contract of InputStream.read(bytes[]),
# readFully() can handle the 0 in its loop
# other apps can decided what to do.
