The JSON output generated by the Hierarchy Builder transformation contains data of the string data type. You must use the Java transformation to convert the string data to binary format before you upload data to Microsoft Azure Data Lake Storage Gen2.
A Java transformation has incoming fields and output fields. Use incoming and output fields as variables in the Java code snippets that you define on the
Java
tab. Incoming fields appear on the
Incoming Fields
tab. By default, the Java transformation inherits all incoming fields from the upstream transformation.
Add a Java transformation to the mapping.
On the
General
tab, enter a name and description for the Java transformation.
On the
Incoming Fields
tab, you can view the incoming fields from the Hierarchy Builder transformation of string data type
On the
Output Fields
tab, add output fields for the output data that you want to pass to the downstream transformation.
