--------------------------------------
Summary: Fetcher: suppress stack for frequent exceptions
Key: NUTCH-2702
URL: https://issues.apache.org/jira/browse/NUTCH-2702
Project: Nutch
Issue Type: Improvement
Components: fetcher
Affects Versions: 1.15
Reporter: Sebastian Nagel
Fix For: 1.16
Fetcher logs the entire Java stack when a fetch fails with an Exception. To
reduce the size of the fetcher logs, frequent exceptions with an obvious reason
should be logged without stack, at least, for the default log level (INFO).
Frequent and obvious exceptions are:
- java.net.UnknownHostException
- java.net.SocketTimeoutException
- java.net.ConnectException
- javax.net.ssl.SSLHandshakeException
Class name and message should be sufficient by default. For debugging the fetch
can be retried with a more verbose log level.
