Hey Abdel,
I renamed it due to your previous hint with the static subclass.
But the SQL Commands still returns:
0: jdbc:drill:> SELECT myintadd(CAST(position_id AS int),CAST(store_id AS int))
FROM cp.`employee.json`;
Error: VALIDATION ERROR: From line 1, column 8 to line 1, column 63: No match
found for function signature myintadd(<NUMERIC>, <NUMERIC>)
So this has to be something wrong with my drill setup?
All I do is to start my drillbit with drillbit.sh start (or restart) and then
start drill-conf where the conf/drill-override.conf contains:
drill.exec: {
cluster-id: "drillbits1",
zk.connect: "localhost:2181"
}
There’s one other thing that seems strange to me with my setup:
Although I set the loglevel in conf/logback.xml to trace the drillbit.log file
does not show any trace outputs.
Am I doing something wrong with my setup?
Thanks
Julian
