问题
I'm currently working on connecting an Azure blob with Pyspark and am encountering difficulties getting the two connected and running. I have installed both required jar files (hadoop-azure-3.2.0-javadoc.jar and azure-storage-8.3.0-javadoc.jar). I set them to be read in my sparkConf by using SparkConf().setAll() and once the I start the session I use:
spark._jsc.hadoopConfiguration().set("fs.azure", "org.apache.hadoop.fs.azure.NativeAzureFileSystem")
spark._jsc.hadoopConfiguration().set("fs.azure.account.key.acctname.blob.core.windows.net", "key")
sdf = spark.read.parquet("wasbs://container@acctname.blob.core.windows.net/")
but it always returns
java.io.IOException: No FileSystem for scheme: wasbs
Any thoughts?
I've followed the following:
