Andras Bokor commented on HADOOP-5943:
--------------------------------------
I agree:
* The current logic does not meet with the Java 7 pattern. In Java 7
try-catch-resources are preferred.
* Misleading. I found some misusages that may cause double calls in
InputStreams. Please see HADOOP-14691 for example.
> IOUtils#copyBytes methods should not close streams that are passed in as
> parameters

> 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.
