Just discovered that if you want to add a JAR file to an HQL statement, the JAR file can’t be at the root of your container. It has to be in a virtual directory. So, for example, this code will not work:
ADD JAR wasb:///csv-serde-1.1.2-0.11.0-all.jar;
But, this code will:
ADD JAR wasb:///user/hdp/share/lib/hive/csv-serde-1.1.2-0.11.0-all.jar;
And, annoyingly, the blob storage browser in Visual Studio doesn’t allow you to create directories, so you’ll need to download something ClumsyLeaf CloudXplorer or the like.
