I have a Scala model class, whose object I want to store it onto Cassandra table.there is a mismatch in the order of column names of Cassandra and Scala class variables declaration.
And there is a additional column in Cassandra table,which is not there in Scala class variables list like (tr_tag Text)
but i am not able to do it.
Data is not getting inserted. Please help me to resolve this.
Model scala class:
class THData() extends Serializable{
var s_id: java.lang.Long = null
var a_id: String = null
var s_typ: String= null
var s_dt: java.util.Date= null
var t_s_id: String= null
var a_s_no: String= null
var avg_sp: java.lang.Float = null
}
Method to insert object into cassandra:
def insert(data: THData) {
var em=sc.parallelize(Seq(data))
em.saveToCassandra("ap", "t_s_data")
}
Cassndra table having column name like below:
sid,aid,styp,sdt,tsid,asno,avgsp,tr_tag
I think you should modify the column names as described in the documentation :
