JDBC Driver Loading Error: Handler processing failed - OutOfMemory: PermGen space


When ingesting data from JDBC sources during configuration of Import Jobs from databases, the error OutOfMemory: PermGen space may be observed. 


Datameer appears to leak the driver classes into the permgen space, eventually overrunning the permgen and causing the server to become unresponsive and requiring a reboot.

This is known internally as DAP-25721. 


To work-around this issue, deplay custom JDBC drivers through the following directory, instead of uploading the JDBC driver via UI
