Weird error with character variables - Spark sql does not support binarytype

[Amit Panda]

i have a simple file/ hive table, a reference table with Subject, Codes (Int) and Names of Apps, on Cloudera. in Tibco data science tool, when I read and use directly, partial or full string matching on the chararray variables crash -- simplest conditions e.g. subject = 'protocol'.. But, if I define & add a new variable subject1, again chararray through variable node, the condition works!! if I were to play with variables, hundreds of them, this cloning across hundreds of them is tiring and frustrating.

I share screenshot of errorfor original variable, spark sql does not support binarytype!!!
