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.
