Built using maven scala plugin on intellij IDEA with Maven 3.3.9. Ran on Azure HDInsight Spark cluster using Yarn.
Spark version: 2.4.0
Scala version: 2.11.12
hbase-spark version: 1.0.0
Description
I am attempting to do a left outer join (though any join with a push down filter causes this issue) between a Spark Structured Streaming DataFrame and a DataFrame read from HBase. I get the following stack trace when running a simple spark app that reads from a streaming source and attempts to left outer join with a dataframe read from HBase:

It appears to be attempting to reference a file called "JavaBytesEncoder$.class" resulting in a NoClassDefFoundError. Interestingly, when I unzipped the jar I found that both "JavaBytesEncoder.class" and "JavaBytesEncoder$.class" exist, but the latter is simply an empty file. This might just be a case of me misunderstanding how Java links classes upon build however.
