Subject [jira] [Created] (BEAM-1832) Potentially unclosed OutputStream in ApexYarnLauncher
Date Wed, 29 Mar 2017 15:51:41 GMT
Ted Yu created BEAM-1832:
----------------------------

             Summary: Potentially unclosed OutputStream in ApexYarnLauncher
                 Key: BEAM-1832
                 URL: https://issues.apache.org/jira/browse/BEAM-1832
             Project: Beam
          Issue Type: Bug
          Components: runner-apex
            Reporter: Ted Yu
            Priority: Minor


Here is an example from createJar():
{code}
      final OutputStream out = Files.newOutputStream(zipfs.getPath(JarFile.MANIFEST_NAME));
      if (!manifestFile.exists()) {
        new Manifest().write(out);
      } else {
        FileUtils.copyFile(manifestFile, out);
      }
      out.close();
{code}
If FileUtils.copyFile throws IOException, out would be left unclosed.
