A UDF source jar and binaries are successfully registered by the Drillbit but when the UDF is called, it throws EigenbaseContextException.
Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while running query.[error_id: "f80cd899-983c-4af7-8c3e-86616294a2e6"
endpoint {

 user_port: 31010
 control_port: 31011
 data_port: 31012
}
error_type: 0
message: "Failure while parsing sql. < ValidationException:[ org.eigenbase.util.EigenbaseContextException: From line 1, column 8 to line 1, column 19 ] < EigenbaseContextException:[ From line 1, column 8 to line 1, column 19 ] < SqlValidatorException:[ No match found for function signature mode(<ANY>) ]"
]
Error: exception while executing query (state=,code=0)

It will be helpful to add a command to list UDFs and UDAFs that Drillbits are aware of.
