----------------------------------------
Summary: Allow setting url connection timeout in Configuration
Key: HADOOP-11276
URL: https://issues.apache.org/jira/browse/HADOOP-11276
Project: Hadoop Common
Issue Type: Improvement
Reporter: Maysam Yabandeh
Priority: Minor
Currently for url resources there is no way to control the http connection
opened by Configuration:
{code}
private Document parse(DocumentBuilder builder, URL url)
throws IOException, SAXException {
if (!quietmode) {
LOG.debug("parsing URL " + url);
}
if (url == null) {
return null;
}
return parse(builder, url.openStream(), url.toString());
}
{code}
If we let this method call a protected method that return a stream object from
a URL, then the application can override such method and set the application
specific connection settings on the URL, like
{code}
URLConnection con = url.openConnection();
con.setConnectTimeout(connectTimeout);
InputStream in = con.getInputStream();
return in;
{code}
Our monitoring tool currently needs to retrieve the conf from many app masters
and the default timeout of 60s is too much, and no way to configure it in the
current implementation of the Configuration.
If there is any +1 for this change I can submit an initial patch.
