So probably CassandraCFData cassandraData = db.getCFData(columnFamily, start, 1000);
did not get any data from Cassandra? Never played with this plugin either Cassandra so I'm afraid I can't help more here! -- David Pilato | Technical Advocate | Elasticsearch.com @dadoonet | @elasticsearchfr Le 8 janvier 2014 at 11:21:26, shamsul haque (shams...@gmail.com) a écrit: CassandraRiver.java:149 contains: logger.info("Starting thread with {} keys", this.keys.rowColumnMap.size()); where rowColumnMap is a map, and may be empty thats why this error comes And at first i build that river module normally and install it as a plugin in ES. But when i ran script: curl -XPUT 'localhost:9200/_river/userinfo/_meta' -d '{ "type" : "cassandra", "cassandra" : { "cluster_name" : "Test Cluster", "keyspace" : "topic_space", "column_family" : "users", "batch_size" : 100, "hosts" : "localhost:9160" }, "index" : { "index" : "userinfo", "type" : "users" } }' same error comes in ES console, same as i have copied from maven console. and it also not fetching data from cassandra to ES. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
