Different update statements on column tables lead to AssertionError: java.lang.AssertionError: "assertion failed: Unexpected nulls=2 for withHeader=false”

The following statement in spark-shell "spark.sql(“update position set VAL115=VAL115*2, version=4 “).collect" leads to the mentioned in the header error. The same assertion error occurs after many other update statements

Looks like you are using the SparkSession instance? spark.sql? Create a snappysession and execute the same.

no, this was snappy session. I have afterwards executed val spark = snappySession just in order to be able to copy my old code
