-------------------------------------------
Summary: ClassPathException sending topN argument for /job/create
using Nutch 2.x RESTApi
Key: NUTCH-2019
URL: https://issues.apache.org/jira/browse/NUTCH-2019
Project: Nutch
Issue Type: Bug
Components: generator
Affects Versions: 2.3
Environment: Nutch 2.3
Reporter: Lewis John McGibbney
Assignee: Lewis John McGibbney
Priority: Minor
Fix For: 2.3.1
Attachments: NUTCH-2019.patch
As described
[http://www.mail-archive.com/user%40nutch.apache.org/msg13549.html|here], the
issues is as follows
Looking at the source I think it was caused by the following line:
topN = (Long) args.get(Nutch.ARG_TOPN);
I managed to get it temporarily "fixed" by replacing the above with the
following:
try{
topN = (Long) args.get(Nutch.ARG_TOPN);
} catch(Exception e) {
topN = Long.parseLong(args.get(Nutch.ARG_TOPN).toString());
LOG.warn("Error: " + e + "test: " + args.get(Nutch.ARG_TOPN));
}
I guess it complains about ClassCastException because JSON stores the argument
as int or string and not long.

Alex
