Close all the streams/files even if it is failed to close one stream/file

Code snippet (RetriableFileCopyCommand.java)

} finally {
      if (mustCloseStream) {
        IOUtils.cleanup(LOG, inStream);
        try {
          if (reader != null)
            reader.close();
          if (compressedIn != null)
            compressedIn.close();
          if (commpressedOut != null)
            commpressedOut.close();
          outStream.close();
        }
        catch(IOException exception) {
          LOG.error("Could not close output-stream. ", exception);
          throw exception;
        }
      }
    }

Currently, If we get any error/exception while closing reader then we are not closing the others outputstream, compressedin and compressedout after that.

Code snippet: (FileUtil.java)

finally {
      compressedOut.close();
      in.close();
      out.close();
      CodecPool.returnCompressor(gzipCompressor);

    }

we should close the reader as well and close all the stream separately.
