-----------------------------------------
Resolution: Fixed
> Overseer.updateState tries to use router name from message but none is sent
> ---------------------------------------------------------------------------
>
> Key: SOLR-5321
> URL: https://issues.apache.org/jira/browse/SOLR-5321
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.5
> Reporter: Shalin Shekhar Mangar
> Assignee: Shalin Shekhar Mangar
> Priority: Minor
> Fix For: 5.0, 4.6
>
>
> Overseer.updateSlice method has the following code:
> {code}
> String router =
> message.getStr(OverseerCollectionProcessor.ROUTER,DocRouter.DEFAULT_NAME);
> List<String> shardNames = new ArrayList<String>();
> //collection does not yet exist, create placeholders if num shards is
> specified
> boolean collectionExists =
> state.getCollections().contains(collection);
> if (!collectionExists && numShards!=null) {
> if(ImplicitDocRouter.NAME.equals(router)){
> getShardNames(shardNames, message.getStr("shards",null));
> numShards = shardNames.size();
> }else {
> getShardNames(numShards, shardNames);
> }
> state = createCollection(state, collection, shardNames, message);
> }
> {code}
> Here it tries to read the router name from the message. Even if we ignore
> that the key to lookup the router is wrong here, the router name is never
> sent in a state message.
> Considering that we don't even support creating a collection with "implicit"
> router from command line, we should stop expecting the parameter.
