Scala-Spark DataFrame Issue Troubleshooting

Job ID: 39242766

Budget: $30 – $250 USD

I am currently facing an issue with a Scala-Spark job. Instead of receiving expected column values, I'm getting column names. This issue is occurring while performing DataFrame operations on JSON files using Spark 3.x.

Key Requirements:
- Extensive experience with Spark 3.x
- Proficiency in Scala and Spark, specifically with DataFrame operations
- Prior experience working with JSON files
- Ability to troubleshoot and fix implementation issues effectively
- Strong understanding of Spark's DataFrame operations and their expected outputs

I am looking for a Principal Data Engineer who can quickly help rectify this issue so I can continue with my project.
