如何将 AsTable 保存到 s3?

How to saveAsTable to s3?

看起来这会出错

df.write()
  .option("mode", "DROPMALFORMED")
  .option("compression", "snappy")
  .mode("overwrite")
  .bucketBy(32,"column")
  .sortBy("column")
  .parquet("s3://....");

有错误

Exception in thread "main" org.apache.spark.sql.AnalysisException: 'save' does not support bucketing right now; at org.apache.spark.sql.DataFrameWriter.assertNotBucketed(DataFrameWriter.scala:314)

我看到 saveAsTable("myfile") 仍然受支持,但它只在本地写入。作业完成后,我如何获取 saveAsTable(...) 输出并将其放在 s3 上?

    You Can use like below:

    df
                .write()
                .option("mode", "DROPMALFORMED")
                .option("compression", "snappy")
                .option("path","s3://....")
                .mode("overwrite")
                .format("parquet")
                .bucketBy(32,"column").sortBy("column")
                .saveAsTable("tableName");

这将创建一个指向 S3 位置的外部 table .option("path","s3://....") 是这里的问题
