从 Azure Databricks 将数据写入 Azure Blob 存储

Question

I was able to mount Azure Blob Container to my Databricks DBFS and was able to read the data as well. While writing, I was able to see the files in the mount point from within databricks, however, it does not reflect in the blob storage. Can someone help?

Answer 1

Are you saving the data frame?

df.write
.option("header", "true")
.format("com.databricks.spark.csv")
.save("/mnt/result/someData.csv")

Answer 2

Chances are that your path is incorrect. Check the mounted path with dbutils.fs.mounts() and ensure it is in your saving path. Also check that your saving path starts with dbfs:/ and not /dbfs/ . Don't hesitate to share your script.
