Cassandra with JDBC river plugin


(Abhishek Mukherjee) #1

Hi Everyone,

I am trying to move data from Cassandra to Elasticsearch. Initially I tried
the cassandra-river at https://github.com/eBay/cassandra-river. However I
got timed out error which I suspect was originating from the Hector API. I
posted a question on ths thread
https://groups.google.com/forum/#!searchin/elasticsearch/cassandra/elasticsearch/4oDbkqK3GVA/W9WLK4SS2MEJ.

Moving on I thought of using the JDBC-river at
https://github.com/jprante/elasticsearch-river-jdbc with a java driver for
cassandra. I followed the mysql example and modified it for cassandra. I
created the river using as follows:

curl -XPUT '192.168.1.103:9200/_river/my_jdbc_river/_meta' -d '{

"type" : "jdbc",
"jdbc" : {
"url" :
"jdbc:cassandra://192.168.1.105:9160/transactionlogdb",
"cql" : "select * from
logs"
}
}'

{"_index":"_river","_type":"my_jdbc_river","_id":"_meta","_version":1,"created":true}

However I don't find any documents being created on the jdbc index. Am I
missing something? Any help or tips is very much appreciated. Thanks is
advance.

Kind Regards,
Abhishek Mukherjee

Checking the Elasticsearch log files I found this.

No suitable driver found for
jdbc:cassandra://192.168.1.103:9160/transactionlogdb
at java.sql.DriverManager.getConnection(DriverManager.java:689)
at java.sql.DriverManager.getConnection(DriverManager.java:247)
at
org.xbib.elasticsearch.river.jdbc.strategy.simple.SimpleRiverSource.getConnectionForReading(SimpleRiverSource.java:133)
at
org.xbib.elasticsearch.river.jdbc.strategy.simple.SimpleRiverSource.execute(SimpleRiverSource.java:271)

However I have placed all the necessary jar files for the driver in
$ES_HOME/plugins/jdbc. Please advice.

Kind Regards
Abhishek

The Cassandra Java Driver is not a JDBC driver.
