Hello, since spark 2.x can not use Phoenix Spark Interpreter to load data,
so I want to use JDBC, but when I want to get a *thin connection*, I got
the following Error info while using *direct connection is ok* ， I ran it
in spark-shell, scala 2.11.8, so can anyone give a solution?
Phoenix : 4.8.1-HBase-1.2
