We try to import our data into SolrCloud using MapReduce Batch Indexing. We face a problem at the reduce phase, that solr.xml cannot be found. We create a 'twitter' collection but looking at the logs, after it failed to load in 'solr.xml', it uses the default one and tries to create 'collection1' (failed) and 'core1' (success) SolrCore. I'm not sure if we need to create our own 'solr.xml' and where to put it (we try to put it at several places but it seems not to load in). Below is the log:
