dedup_job java.lang.UnsatisfiedLinkError

Comienza reproduciendo dedup_job en el entorno indicado de conda, Spark 3.0.1, Hadoop 2.7, Java 8 y Windows, y luego compáralo con sample_job y Korean_job. Inspecciona el punto de entrada de dedup_job y determina si el trabajo de deduplicación coreano solicitado forma parte del mismo trabajo. Se considera terminado cuando el trabajo se ejecuta sin el UnsatisfiedLinkError indicado y la solicitud del conjunto de datos coreano ha sido atendida.

Hello I am getting this error while running dedup_job.

I am able to run sample_job and Korean_job but when I get this error in dedup_job.

I am using conda env, spark 3.0.1 with hadoop 2.7 with java SDK 8 on Windows. My system variables are set properly.

Need help

Kindly add a deduplication job for the Korean dataset.
