To produce this issue we don't need several drillbits, it's just enough to issue several concurrent create function commands. As for this test case, I just mock method that updates remote function registry to throw VersionMismatchException two times and then call this method for real. > After the dynamic registration of multiple jars simultaneously not all UDFs > were registered > ------------------------------------------------------------------------------------------- > > Key: DRILL-5044 > URL: https://issues.apache.org/jira/browse/DRILL-5044 > Project: Apache Drill > Issue Type: Bug > Components: Functions - Drill > Affects Versions: 1.9.0 > Reporter: Roman > Assignee: Arina Ielchiieva > > I tried to register 21 jars simultaneously (property 'udf.retry-attempts' = > 30) and not all jars were registered. As I see in output, all function were > registered and /staging directory was empty, but not all of jars were moved > into /registry directory. > For example, after simultaneously registration I saw "The following UDFs in > jar test-1.1.jar have been registered: [test1(VARCHAR-REQUIRED)" message, but > this jar was not in /registry directory. When I tried to run function test1, > I got this error: "Error: SYSTEM ERROR: SqlValidatorException: No match found > for function signature test1(<CHARACTER>)". And when I tried to reregister > this jar, I got "Jar with test-1.1.jar name has been already registered". -- This message was sent by Atlassian JIRA (v6.3.4#6332)
