Hello all,
i'm using spark 1.2 with spark cassandra connector 1.2.3,
i'm trying to update somme rows of table:
example:
*CREATE TABLE myTable (
a text,
b text,
c text,
date timestamp,
d text,
e text static,
f text static,
PRIMARY KEY ((a, b, c), date, d)
) WITH CLUSTERING ORDER BY (date ASC, d ASC)*
*val interactions = sc.cassandraTable[(String, String, String, DateTime,
String, String)]("keySpace", "myTable").
select("a","b","c","date", "d", "e","f")
val empty = interactions.filter(r => r._6 == null).cache()
empty.count()*
I just count the number of rows containing null for "e" and the remplace
them by the value of "b"
* val update_inter = empty.map( r => (r._1,r._2, r._3, r._4, r._5, r._2))
update_inter.saveToCassandra("keySpace", "myTable",
SomeColumns("a","b","c","date", "d", "e", "f"))*
this works when i check in cqlsh , but i still get the value null when i
request the same rows by spark cassandra .
Is this a bug in spark cassandra connector? Thanks for your help.
