> When trying to use scalar casting to get element from a list, unexpected mapreduce tasks are launched instead of CP mode. The scenario is to replace *C = 1* with *C = as.scalar(hyperparams["C"])* inside the {{_gradient function_}} found in {{_src/test/scripts/functions/paramserv/mnist_lenet_paramserv.dml_}}. And then the problem could be reproduced by launching the method {{_testParamservBSPBatchDisjointContiguous_}} inside class _{{org.apache.sysml.test.integration.functions.paramserv.ParamservLocalNNTest}}_

> [~mboehm7], if possible, could you take a look on this? And I've double checked the creation of execution context in {{ParamservBuiltinCPInstruction}}. But it is instance of ExecutionContext not SparkExecutionContext.
