[jira] [Commented] (SPARK-19123) KeyProviderException when reading
Azure Blobs from Apache Spark
[ https://issues.apache.org/jira/browse/SPARK-19123?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15808663#comment-15808663 ]
Shuai Lin commented on SPARK-19123:
-----------------------------------
IIUC {{KeyProviderException}} means the storage account key is not configured properly. Are you sure the way you specify the key is correct? Have you checked the azure developer docs for it?
BTW I don't think this is an "critical issue", so I changed it to "minor".

> Key: SPARK-19123
> URL: https://issues.apache.org/jira/browse/SPARK-19123
> Project: Spark
> Issue Type: Question
> Components: Input/Output, Java API
> Affects Versions: 2.0.0
> Environment: Apache Spark 2.0.0 running on Azure HDInsight cluster version 3.5 with Hadoop version 2.7.3
> Reporter: Saulo Ricci
> Priority: Minor
> Labels: newbie

> I created a Spark job and it's intended to read a set of json files from a Azure Blob container. I set the key and reference to my storage and I'm reading the files as showed in the snippet bellow:
> {code:java}
> SparkSession
> sparkSession =
> SparkSession.builder().appName("Pipeline")
> .master("yarn")
> .config("fs.azure", "org.apache.hadoop.fs.azure.NativeAzureFileSystem")
> .config("fs.azure.account.key.<storage_name>.blob.core.windows.net","<storage_key>")
> .getOrCreate();
> Dataset<Row> txs = sparkSession.read().json("wasb://path_to_files");
> {code}
> The point is that I'm unfortunately getting a `org.apache.hadoop.fs.azure.KeyProviderException` when reading the blobs from the azure storage. According to the trace showed bellow it seems the header too long but still trying to figure out what exactly that means:

> I'm using a Apache Spark 2.0.0 cluster set on top of a HDInsight Azure cluster and I'd like to find a solution to this problem. I appreciate any suggestion.
