Hello, I’m using Spark 3.1.1 and cannot yet update to a newer version. I have got a data frame with a single column of DataTypes.BinaryType where each row contains a byte array with generated binary data. I try now to write this data in a single file with
mydataframe.coalesce( 1 ) .write() .mode( SaveMode.Overwrite ) .format( "binaryFile" ) .save( „s3a://mybucket/myfile <s3a://mybucket/myfile>.bin“ ); But I get the error message „java.lang.UnsupportedOperationException: Write is not supported for binary file data source“. So my question is, how can I add to my current spark version a binary writer? I have seen this tutorial https://levelup.gitconnected.com/easy-guide-to-create-a-write-data-source-in-apache-spark-3-f7d1e5a93bdb <https://levelup.gitconnected.com/easy-guide-to-create-a-write-data-source-in-apache-spark-3-f7d1e5a93bdb> Is there an existing component which I can user under my version? Thanks a lot for help
