[jira] [Created] (DRILL-5274) Exception thrown in Drillbit shutdown
in UDF cleanup code
Paul Rogers created DRILL-5274:
----------------------------------
Summary: Exception thrown in Drillbit shutdown in UDF cleanup code
Key: DRILL-5274
URL: https://issues.apache.org/jira/browse/DRILL-5274
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.10
Reporter: Paul Rogers
Assignee: Arina Ielchiieva
I ran a very simple query: a single-line text file in an embedded Drillbit. On Drillbit shutdown, the following occurred:
{code}
25328 DEBUG [main] [org.apache.drill.exec.server.Drillbit] - Shutdown begun.

{code}
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}
