[jira] [Commented] (MAPREDUCE-3649) Job End notification gives an
error on calling back.
[ https://issues.apache.org/jira/browse/MAPREDUCE-3649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13182960#comment-13182960 ]
Alejandro Abdelnur commented on MAPREDUCE-3649:
-----------------------------------------------
Looking at the code in the JobNotifier class:
{code}
URLConnection conn = urlToNotify.openConnection();
conn.setConnectTimeout(5*1000);
conn.setReadTimeout(5*1000);
conn.setAllowUserInteraction(false);
InputStream is = conn.getInputStream();
conn.getContent();
is.close();
{code}
Instead it should be
{code}
HttpURLConnection conn = (HttpURLConnection) urlToNotify.openConnection();
conn.setConnectTimeout(5*1000);
conn.setReadTimeout(5*1000);
conn.setAllowUserInteraction(false);
if (conn.getResponseCode() != HttpURLConnection.HTTP_OK) {
//LOG WARNING
}
{code}
