Apache Drill: Local udf directory must be writable for application user error

Question

I'm trying to get Drill up and running on my machine. However, whenever I enter drill-embedded mode (bin/drill-embedded on Bash), I get this error:

 Error: Failure in starting embedded Drillbit: java.lang.IllegalStateException: Local udf directory [/tmp/drill/udf/udf/local] must be writable for application user (state=,code=0)

If I try to run a query at this point, it'll give back:

No current connection 

Any idea how to fix this? I've tried starting with a clean shell with no luck. Is it a permissions issue?

Answer 1

You have to give the directory /tmp/drill/udf/udf/local write access. Since it is a directory in /tmp, you might need root access to give permissions, or you will have to use sudo. To give permission, use this:

chmod 777 -R /tmp/drill/udf/udf/local

Also make sure the user is having at least read permission on the parent directories, otherwise you will get a permission denied error again.
