After a few runs, throws ClassCastException: org.gridgain.grid.kernal.processors.cache.distributed.dht.atomic.GridDhtAtomicCache cannot be cast to org.gridgain.grid.kernal.processors.cache.distributed.near.GridNearCacheAdapter #78

Java8 code: (https://github.com/ceefour/lumen-kb/blob/e50b8fc0690c078fcec1c037be9496f1dc10937f/cli/src/main/java/id/ac/itb/ee/lskk/lumen/yago/YagoLabelLookupCli.java)

String upLabel = "Muhammad";

try (Grid grid = GridGain.start(YagoLabelLookupCli.class.getResource("yago.gridgain.xml"))) {
    GridCache<String, String> labelCache = grid.cache("yagoLabel");
//          labelCache.queries().createScanQuery(null).execute((GridClosure<Entry<String, String>, String>) (it) ->
//              it.getValue().equalsIgnoreCase(upLabel) ? it.getKey() : null);
    log.info("Finding resource for label '{}'...", upLabel);
    Collection<String> founds = labelCache.queries().createScanQuery(null).execute(new GridReducer<Entry<String, String>, String>() {
        String id;

        @Override
        public boolean collect(Entry<String, String> e) {
            if (e.getValue().equalsIgnoreCase(upLabel)) {
                id = e.getKey();
                return false;
            } else {
                return true;
            }
        }

        @Override
        public String reduce() {
            return id;
        }
    }).get();

    log.info("Found for {}: {}", upLabel, founds);
}

After a few edits and runs, GridGain throws the following error. This error never happens on the first invocation (i.e. after starting 2 nodes, then running the compute)

We are trying to reproduce this issue. Can you provide content of your yago.gridgain.xml configuration file? You can use http://pastebin.com/ to paste your code.

ceefour commented 10 years ago

Sure, here's it: https://github.com/ceefour/lumen-kb/blob/e50b8fc0690c078fcec1c037be9496f1dc10937f/cli/src/main/resources/id/ac/itb/ee/lskk/lumen/yago/yago.gridgain.xml

If I can find reproducible steps I'll let you know.

agoncharuk commented 10 years ago

This is a pretty rare bug which is reproduced when using full-scan query on changing topology. It was fixed and will be available in upcoming 6.2.0 release. As a workaround, you can now enable NEAR_PARTITIONED distribution mode on all nodes, or start your 'client' node that initiates query in CLIENT_ONLY or NEAR_ONLY distribution mode.

Thank you! Wow, you're good...
