I'm using delta lake on using pyspark by submitting below command
spark-sql --packages io.delta:delta-core_2.12:0.8.0 --conf "spark.sql.extensions=io.delta.sql.DeltaSparkSessionExtension" --conf "spark.sql.catalog.spark_catalog=org.apache.spark.sql.delta.catalog.DeltaCatalog"
System Specs:
- Spark - 3.0.3
- scala - 2.12.10
- java - 1.8.0
- hadoop - 2.7
i'm looking at reference blog https://docs.delta.io/latest/quick-start.html https://www.confessionsofadataguy.com/introduction-to-delta-lake-on-apache-spark-for-data-engineers/
but when I use spark without the delta config spark works fine.
