【问题描述】：
我在写入 spark 结构化流数据帧时遇到错误 - 请告诉我在运行此代码时我做错了什么-
这里 df 正在从 s3://abc/testing 位置读取数据，我正在使用 spark 流将这个数据帧写入不同的 s3 位置-
val q = df .writeStream
.trigger(Trigger.Once)
.option("checkpointLocation", "s3://abc/checkpoint")
.foreachBatch { (batchDF: DataFrame, batchId: Long) =>
batchDF
.write
.mode(SaveMode.Append)
.parquet("s3://abc/demo")
}.start()
q.processAllAvailable()
q.stop()
在运行上面的代码时出现以下错误 -
org.apache.spark.sql.streaming.StreamingQueryException: Job aborted.

-
好吧，考虑到您正在写入 S3，连接可能存在问题，您可以检查一下。但在我看来，主要的异常消息丢失了，你确定你发布了整个堆栈跟踪吗？
-
@Filip 我添加了整个错误消息，如果你能帮助我
