> The following methods in IOUtils close the streams that are passed in as parameters. Calling these methods can easily trigger findbug OBL: Method may fail to clean up stream or resource (OBL_UNSATISFIED_OBLIGATION). A good practice should be to close a stream in the same method where the stream is opened.
> public static void copyBytes(InputStream in, OutputStream out, int buffSize, boolean close)
> public static void copyBytes(InputStream in, OutputStream out, Configuration conf, boolean close)
> These methods should be deprecated.
