Note the ClassNotFoundException:
Caused by: java.lang.ClassNotFoundException: com.gemstone.gemfire.pdx.internal.PdxType
This same error can also be thrown when importing data that was exported from GemFire 8.2.2 or later 8 version.
Environment
Cause
Whether seeing the exception after upgrading or when importing data that was exported from GemFire 8.2.2 or later 8 version, this issue is caused by not having the geode-old-client-support-9.x.x.jar on the class path. This Jar file contains the classes that are needed for upgrading the internal GemFire classes and packages from the previous com.gemstone.gemfire in version 8.2.x to the new com.geode in GemFire 9.
Resolution
Make sure that geode-old-client-support-9.x.x.jar is available on the server and that the jar is added to the class path of GemFire. You can find the class path used by GemFire in the log file configuration header to check.
