ClassNotFoundException when trigger is fired
Dear All
I use cassandra trigger to detect data change in DB and usually it works.
But sometime I get ClassNotFoundException when trigger is fired.
Following is what I did
1. create class which implement ITrigger interface. ex)class name is TestTrigger.java
2. create jar file and put it under conf/triggers ex)jar file name is TestTrigger.jar
3. start cassandra
4. I can find following log. Looks like jar file is loaded successfully
INFO [OptionalTasks:1] 2017-11-30 03:55:43,541 CustomClassLoader.java:87 - Loading new jar /home/tnarita/cassandra/conf/triggers/TestTrigger.jar
5. login cql and create trigger for test table.
6. insert value into test table
7. trigger is fired.
8. I got ClassNotFoundException. following is the log
java.lang.RuntimeException: Exception while executing trigger on table with ID: 1cb6a5a0-cb00-11e7-a737-49047aea57a8

When I get this issue, restarting cassandra resolve this issue.
TestTrigger.java output dummy log in static initializer. When I don't get this issue, I can find dummy log after Step4.
But when I get this issue, I can't find it.
I checked system.log and debug.log but there weren't any error log which indicate jar loading failure.
I would like to know whether this is known issue or not.
Does anyone know this issue?

Posted by Jeff Jirsa <jj...@gmail.com>.
Can you open a JIRA please, would be great if you have a trivial trigger to
help us repro (so whoever goes to fix it doesnt need to write a fake
trigger class)?

RE: ClassNotFoundException when trigger is fired

Hi,
Thanks for your replay.
I put jar file under conf/triggers before starting Cassandra then I could found following log
INFO [OptionalTasks:1] 2017-11-30 03:55:43,541 CustomClassLoader.java:87 - Loading new jar /home/tnarita/cassandra/conf/triggers/TestTrigger.jar
It looks like my jar files is added to Cassandra's classloader but when Cassandra call my class, sometimes ClassNotFoundException happen.
If I reboot Cassandra , I don't get ClassNotFoundException and cassandara can call my class.
So, I suspect function related to loading jar file have bugs.
Thanks,
Tsubasa Narita

Hi,
I have a custom secondary index that works well with Cassandra, I put the jar file in Cassandra's lib folder before starting Cassandra, maybe you can try to do the same thing?
I don't think that Cassandra's class loader is dynamic, you need to have your jars in the classpath before starting Cassandra.
