Subject [jira] [Commented] (CONNECTORS-1312) jcifs.smb.SmbException: Connection reset by peer: socket write error
Date Wed, 04 May 2016 21:45:13 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15271490#comment-15271490
] 

Karl Wright commented on CONNECTORS-1312:
-----------------------------------------

SmbAuthException errors we *do* want to skip the document and continue.  This is because individual
documents have individual authorization and failing on one document does not mean failing
on all.  We have caught this situation for many years:

{code}
      catch (jcifs.smb.SmbAuthException e)
      {
        Logging.connectors.warn("JCIFS: Authorization exception reading version information
for "+documentIdentifier+" - skipping");
        if(e.getMessage().equals("Logon failure: unknown user name or bad password."))
            throw new ManifoldCFException( "SmbAuthException thrown: " + e.getMessage(), e
);
        else {
            activities.deleteDocument(documentIdentifier );
            continue;
          }
      }

{code}

> Current workaround - to start the job again (manually or by the scheduler).
> It is clear, that there are many errors, when it makes no sense to skip a failed URL
and continue the job, e.g.:
> {code}
> Error: SmbAuthException thrown: Logon failure: unknown user name or bad password.
> {code}
> I'm thinking about a general solution, like defining a list (through the UI or properties.xml)
with non severe exceptions, like "file busy" or "symlink detected" etc, so the admins would
be able to specify, when the crawler should stop and when it should retry, skip and go further.
> What do you think?
> Thank you!
