Paul Rogers commented on DRILL-5274:
------------------------------------
The following patch makes the problem go away, but I'm not sure if the above is
an indication of deeper problems.
{code}
public class FunctionImplementationRegistry implements FunctionLookupContext,
AutoCloseable {
...
public void close() {
if (deleteTmpDir) {
...
} else {
try {
File dir = new File(localUdfDir.toUri().getPath());
if (dir.exists()) {
FileUtils.cleanDirectory(dir);
}
...
}
}
{code}
> Exception thrown in Drillbit shutdown in UDF cleanup code

> Key: DRILL-5274

> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.10
> Reporter: Paul Rogers
> Assignee: Arina Ielchiieva
> Priority: Minor
>
> I ran a very simple query: a single-line text file in an embedded Drillbit.
> The UDF directory was placed in /tmp. During the run, the directory was
> deleted. On Drillbit shutdown, the following occurred:
> {code}
