Hi there, I'm tweaking hive thrift server and spart session to provide custom sql capabilities, and i came across java.lang.ClassNotFoundException to load customer session builder.
What i found is that the customer session builder is tried to load by MutableURLClassLoader. I have no idea about why my customer session builder is not visible to this class loader. It's happening when opening session. I've got this root cause stack trace : Caused by: java.lang.ClassNotFoundException: com.xxx.XXXSessionStateBuilder at java.net.URLClassLoader.findClass(URLClassLoader.java:382) at java.lang.ClassLoader.loadClass(ClassLoader.java:418) at java.lang.ClassLoader.loadClass(ClassLoader.java:351) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at org.apache.spark.util.Utils$.classForName(Utils.scala:207) at com.xxx.XXXSparkSession$.com$xxx$XXXSparkSession$$instantiateSessionState(XXXSparkSession.scala:724) Any idea about this. TIA. Jason
