Thread:Extension talk:Lucene-search/Help - port 8123 refusing all connections after Linux update & reboot/reply (9)

OK, I downloaded the lucene-search Java source, added some debug output, and recompiled it. Here is more data.


 * On our system, MediaWiki runs on one server (wikihost) and Lucene on another (km105).
 * The problem is that GlobalConfiguration.isSearcher is returning false.
 * In GlobalConfiguration, the hostAddr and hostName variables are set correctly to 127.0.0.1 and the true hostname (km105). However, in the isSearcher function body, both search.get(hostAddr) and search.get(hostName) are null.
 * On a different working Lucene system in my company, search.get(hostName) is non-null.
 * I see only one line where the "search" hashtable gets set, in function processSearchRoles (search.put(host,hostroles)). I added some debugging, and this is getting called only for the MediaWiki host (wikihost) and not for the search host (km105).

Here is the debug output of lsearchd:

Trying config file at path /home/danb/.lsearch.conf Trying config file at path /home/danb/src/lsearch.conf setHost hostAddr = 127.0.0.1 setHost hostName = km105 0   [main] INFO  org.wikimedia.lsearch.util.Localization  - Reading localization for En 755  [main] INFO  org.wikimedia.lsearch.interoperability.RMIServer  - RMIMessenger bound isIndexer hostAddr = 127.0.0.1 isIndexer hostName = km105 isIndexer index.get hostAddr = null isIndexer index.get hostName = [*] isSearcher hostAddr = 127.0.0.1 isSearcher hostName = km105 isSearcher search.get hostAddr = null isSearcher search.get hostName = null   (NOTE: This seems to be the problem.) 758 [Thread-1] INFO  org.wikimedia.lsearch.frontend.HTTPIndexServer  - Indexer started on port 8321

Here is lsearch-global.conf, which is unchanged since before the problem started:

And here is lsearch.conf:

Can you suggest any other debug output I can add to Lucene so it helps find the problem?
