I am having a strange issue occur while utilizing the solr_query handler to make queries in Cassandra on my terminal. When I perform normal queries on my table, I am having no issues, but when I use solr_query I get the following error: Unable to complete request: one or more nodes were unavailable. Other individuals who have experienced this problem seem unable to do any queries on their data whatsoever, whether or not it is solr_query. My problem only persists while using that handler. Can anyone give me a suggestion for what the issue may be with my solr node. ALSO -- I can do queries off

I have DSE spark cluster with 2 nodes. One DSE analytics node with spark cannot start after I install it. Without spark it starts just fine. But on my other node spark is enabled and it can start and works just fine. Why is that and how can I solve that? Thanks. Here is my error log: ERROR [main] 2016-02-27 20:35:43,353 CassandraDaemon.java:294 - Fatal exception during initialization org.apache.cassandra.exceptions.ConfigurationException: Cannot start node if snitch's data center (Analytics) differs from previous data center (Cassandra). Please fix the snitch configuration, decommission and

I have two table with below model: CREATE TABLE IF NOT EXISTS INV ( CODE TEXT, PRODUCT_CODE TEXT, LOCATION_NUMBER TEXT, QUANTITY DECIMAL, CHECK_INDICATOR BOOLEAN, VERSION BIGINT, PRIMARY KEY ((LOCATION_NUMBER, PRODUCT_CODE))); CREATE TABLE IF NOT EXISTS LOOK_INV ( LOCATION_NUMBER TEXT, CHECK_INDICATOR BOOLEAN, PRODUCT_CODE TEXT, CHECK_INDICATOR_DDTM TIMESTAMP, PRIMARY KEY ((LOCATION_NUMBER), CHECK_INDICATOR, PRODUCT_CODE)) WITH CLUSTERING ORDER BY (CHECK_INDICATOR ASC, PRODUCT_CODE ASC); I have a business operation where i need to update CHECK_INDICATOR in both the tables and QUANTITY in INV

Solved I was testing update on 3 nodes, and the time on one of those nodes was 1 second behind, so when update a row, the write time is always behind the timestamp, cassandra would not update the rows. I sync all nodes time, and the issue fixed. Edit: I double checked the result, all insertions are succeed, partial updates failed. There's no error/exception messages I have a cassandra cluster(Cassandra 2.0.13) which contains 5 nodes. Using python(2.6.6) cassandra driver(2.6.0c2) for inserting data into database. my server systems are Centos6.X The following code is how i connect to cassandra

It seems that the unique id for vertices is community_id in DSE Graph. I have found that this works (id is long) : v = g.V().has("VertexLabel","community_id",id).next() none of those work: v = g.V("community_id",id).next() v = g.V("community_id","VertexLabel:"+id).next() v = g.V(id).next() v = g.V().hasId(id).next() v = g.V().hasId("VertexLabel:"+id).next() v = g.V("VertexLabel:"+id).next() Edit After some investigation I found that for a vertex v, v.id() returns a LinkedHashMap: Vertex v = gT.next(); Object id = v.id(); System.out.println(id); System.out.println(id.getClass()); System.out

I start my DataStax cassandra instance with Spark: dse cassandra -k I then run this program (from within Eclipse): import org.apache.spark.sql.SQLContext import org.apache.spark.SparkConf import org.apache.spark.SparkContext object Start { def main(args: Array[String]): Unit = { println("***** 1 *****") val sparkConf = new SparkConf().setAppName("Start").setMaster("spark://127.0.0.1:7077") println("***** 2 *****") val sparkContext = new SparkContext(sparkConf) println("***** 3 *****") } } And I get the following output ***** 1 ***** ***** 2 ***** Using Spark's default log4j profile: org/apache
