-----------------------------------
Summary: Backported refactor cause
Key: SPARK-10377
URL: https://issues.apache.org/jira/browse/SPARK-10377
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.4.2
Reporter: Frode Sormo
The backport in SPARK-7289 and SPARK-9949 includes the refactor of TakeOrdered
to TakeOrderedAndProject, which breaks code that refers to TakeOrdered. In a
minor version update that is perhaps not expected - specifically, the Cassandra
connector refers to this by name and no longer works.
Example use case it to use the Cassandra connector in Scala and creating a
CassandraSQLContext:
import com.datastax.spark.connector._
import sqlContext.implicits._
import org.apache.spark.sql.cassandra.CassandraSQLContext
val cassandraSQLContext = new CassandraSQLContext(sc);
java.lang.NoSuchMethodError:
org.apache.spark.sql.cassandra.CassandraSQLContext$$anon$1.TakeOrdered()Lorg/apache/spark/sql/execution/SparkStrategies$TakeOrdered$;
at
org.apache.spark.sql.cassandra.CassandraSQLContext$$anon$1.<init>(CassandraSQLContext.scala:90)
at
org.apache.spark.sql.cassandra.CassandraSQLContext.<init>(CassandraSQLContext.scala:85)
(Source code link:
https://github.com/datastax/spark-cassandra-connector/blob/v1.4.0-M3/spark-cassandra-connector/src/main/scala/org/apache/spark/sql/cassandra/CassandraSQLContext.scala)
This is with version 1.4.0M3 of the Datastax Cassandra connector, but affects
other 1.4 versions as well.
Issue has also been reported to Datastax, here:
