Description

IOUtils.java

try {
      copyBytes(in, out, buffSize);
    } finally {
      if(close) {
        out.close();
        in.close();
      }
    }

In the above code if any exception throws from the out.close() statement, in.close() statement will not execute and the input stream will not be closed.

Issue Links

• is duplicated by: HDFS-4588 DFSTestUtil.appendFile() should close the output stream on completion.
• relates to: HADOOP-7437 IOUtils.copybytes will suppress the stream closure exceptions.
