6. def checkFileSystem(uri: URI, hadoopConfig: Configuration): Unit

   

   Given a URI, verify that the Hadoop FileSystem for that URI is not the S3 block FileSystem.

   Given a URI, verify that the Hadoop FileSystem for that URI is not the S3 block FileSystem. spark-snowflakedb cannot use this FileSystem because the files written to it will not be readable by Snowflake (and vice versa).

7. def checkThatBucketHasObjectLifecycleConfiguration(tempDir: String, tempDirStorageType: FSType, s3Client: AmazonS3Client): Unit

   

   Checks whether the S3 bucket for the given UI has an object lifecycle configuration to ensure cleanup of temporary files.

   Checks whether the S3 bucket for the given UI has an object lifecycle configuration to ensure cleanup of temporary files. If no applicable configuration is found, this method logs a helpful warning for the user.

14. def fixS3Url(url: String): String

    

    Snowflake COPY and UNLOAD commands don't support s3n or s3a, but users may wish to use them for data loads.

    Snowflake COPY and UNLOAD commands don't support s3n or s3a, but users may wish to use them for data loads. This function converts the URL back to the s3:// format.

15. def fixUrlForCopyCommand(url: String): String

    

    Converts url for the copy command.

    Converts url for the copy command. For S3, convert s3a|s3n to s3. For Azure, convert the wasb: url to azure: url.

    url

    the url to be used in hadoop/spark

    returns

    the url to be used in Snowflake
