[GitHub] [hadoop] ahmarsuhail opened a new pull request #3905: HADOOP-16155. S3AInputStream read(bytes[]) to not retry on read failure

ahmarsuhail opened a new pull request #3905:
URL: https://github.com/apache/hadoop/pull/3905


   ### Description of PR
   
   Jira: https://issues.apache.org/jira/browse/HADOOP-16155
   
   When an error happens on read, do not reopen the stream.
   
   For the unit tests I've changed the order of super.read() and trigger failure. This is because previously the failure would happen after the read actually executed and so the buffer would not be empty and we couldn't assert on the buffer being empty in case of failures.
   
   I've also added a new variable triggerGetObjectFailure. This will not trigger a get object failure in case of testInputStreamReadFullyRetryForException. This is because since we are removing retries from read(bytes[]), readFully() will call read(bytes[]) after each failure which will then call lazySeek() every time. The get object failure ends up being thrown in lazySeek() which does not retry and so readFully does not complete.
   
   ### How was this patch tested?
   
   Tested in eu-west-1 by running
   
   ```
   mvn -Dparallel-tests -DtestsThreadCount=16 clean verify
   ```
