Thingworx Analytics - Exception while creating a dataset

[jrajesh]

Hi,

I have a dataset with 4607 columns and 2523 rows. While creating a dataset using Analytics builder, I am getting the following exception:

JaninoRuntimeException: Constant pool for class org.apache.spark.sql.catalyst.expressions.GeneratedClass$SpecificUnsafeProjection has grown past JVM limit of 0xFFFF

Any idea?

Thanks and Regards,

Jyothi

Hi Jyothi Rajesh​

could you please confirm which version of Thinworx Analytics you are using. Have you checked is there any space in the names of Json and csv file.

Please see the below article:

We should not have space or special character in column name in csv file. Do let me know in case of any question.

Regards,
