Any suggestion why I get this error on z_isMatch ? Please advise.
Same notebook worked fine in first iteration but started getting this error from second iteration. Now, getting same error even I use same notebook on different data set in first iteration also.

I have resolved this issue. Problem was with panda datafram utility to convert into marked parquet file ( matched) over new data set. I have to re-write the code and used Spark-datafram utility to convert into marked parquet file .
trainMatch job also worked fine.
