Subject [jira] [Created] (HADOOP-16282) AvoidFileStream to improve performance

-------------------------------------

             Summary: AvoidFileStream to improve performance
                 Key: HADOOP-16282
                 URL: https://issues.apache.org/jira/browse/HADOOP-16282
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Ayush Saxena
            Assignee: Ayush Saxena


The FileInputStream and FileOutputStream classes contains a finalizer method which will cause
garbage collection pauses. See [JDK-8080225|https://bugs.openjdk.java.net/browse/JDK-8080225]
for details.

The FileReader and FileWriter constructors instantiate FileInputStream and FileOutputStream,
again causing garbage collection issues while finalizer methods are called.
