[FIXED] Im trying to read a csv file from GCS bucket using spark and writing as delta lake(path in GCS) but not able to do write operation

Issue

Im trying in IntelliJ and have added the dependency in pom.xml file.

        <dependency>
            <groupId>io.delta</groupId>
            <artifactId>delta-core_2.12</artifactId>
            <version>1.2.1</version>
        </dependency>

Below are the code used:

val df_gcs = spark.read.format("csv").csv(sourcepath )

df_gcs.write.format("delta").save(save_path)

Getting Below error:

Solution

Changed the version as 1.0.0 and it fixed the issue.

    <dependency>
        <groupId>io.delta</groupId>
        <artifactId>delta-core_2.12</artifactId>
        <version>1.0.0</version>
    </dependency>
