xuekang created YARN-8311: ----------------------------- Summary: Too many ports are occupied when AM UI is accessed Key: YARN-8311 URL: https://issues.apache.org/jira/browse/YARN-8311 Project: Hadoop YARN Issue Type: Bug Components: webapp Affects Versions: 2.7.2 Reporter: xuekang
If someone open the AM UI when the app is running, the RM periodically fetch the page from AM and return to the user. But the connection between RM and AM is created every time and is not closed instantly. So after some time, lots of ports are occupied, especially for long-running services. When another access comes, there may be an error: 2018-05-17 11:33:14,567 INFO org.apache.http.impl.client.DefaultHttpClient: I/O exception (java.net.BindException) caught when connecting to the target host: Address already in use Actually, it is the same problem as YARN-1703 , but I don't know why it was cancelled by YARN-3217. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
