### Search before asking - [X] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened The official [documentation](https://seatunnel.apache.org/docs/seatunnel-engine/separated-cluster-deployment/#45-class-loader-cache-mode) specifies that the default value for classloader-cache-mode is true. However, upon inspection of the internal code in ServerConfigOptions.class, the CLASSLOADER_CACHE_MODE default value is set to false. As a result, when running the SeaTunnel Server with default settings, the ClassLoader cache mode is not enabled. This causes the ClassLoader to repeatedly create and release instances for each job, leading to OutOfMemoryError: Metaspace issues. I believe the default value of CLASSLOADER_CACHE_MODE should be updated to true to align with the documentation and prevent unnecessary ClassLoader creation and memory issues. ### SeaTunnel Version 2.3.8 ### SeaTunnel Config ```conf seatunnel: engine: history-job-expire-minutes: 1440 backup-count: 1 queue-type: blockingqueue print-execution-info-interval: 60 print-job-metrics-info-interval: 60 slot-service: dynamic-slot: true checkpoint: interval: 10000 timeout: 60000 storage: type: hdfs max-retained: 3 plugin-config: namespace: /tmp/seatunnel/checkpoint_snapshot storage.type: hdfs fs.defaultFS: file:///tmp/ # Ensure that the directory has written permission telemetry: metric: enabled: true ``` ### Running Command ```shell ./bin/seatunnel-cluster.sh -d -r master ``` ### Error Exception ```log 2024-12-10 16:23:43,080 ERROR [o.a.s.e.s.TaskExecutionService] [seatunnel-coordinator-service-27] - [localhost]:5801 [seatunnel] [5.1] TaskGroupID : taskGroupLocation is null deploy error with Exception: java.lang.OutOfMemoryError: Metaspace 2024-12-11 09:51:17,878 WARN [Log4j2HttpPostCommandProcessor] [hz.main.cached.thread-19] - [localhost]:5801 [seatunnel] [5.1] An error occurred while handling request HttpCommand [HTTP_POST]{uri='/hazelcast/rest/maps/submit-jobs'}AbstractTextCommand[HTTP_POST]{requestId=0} org.apache.seatunnel.api.table.factory.FactoryException: ErrorCode:[API-06], ErrorDescription:[Factory initialize failed] - Unable to create a source for identifier 'LocalFile'. at org.apache.seatunnel.api.table.factory.FactoryUtil.createAndPrepareSource(FactoryUtil.java:101) ~[seatunnel-starter.jar:2.3.6] at org.apache.seatunnel.engine.core.parse.MultipleTableJobConfigParser.parseSource(MultipleTableJobConfigParser.java:361) ~[seatunnel-starter.jar:2.3.6] at org.apache.seatunnel.engine.core.parse.MultipleTableJobConfigParser.parse(MultipleTableJobConfigParser.java:209) ~[seatunnel-starter.jar:2.3.6] at org.apache.seatunnel.engine.server.rest.RestJobExecutionEnvironment.getLogicalDag(RestJobExecutionEnvironment.java:85) ~[seatunnel-starter.jar:2.3.6] at org.apache.seatunnel.engine.server.rest.RestJobExecutionEnvironment.build(RestJobExecutionEnvironment.java:108) ~[seatunnel-starter.jar:2.3.6] at org.apache.seatunnel.engine.server.rest.RestHttpPostCommandProcessor.handleSubmitJob(RestHttpPostCommandProcessor.java:133) ~[seatunnel-starter.jar:2.3.6] at org.apache.seatunnel.engine.server.rest.RestHttpPostCommandProcessor.handle(RestHttpPostCommandProcessor.java:82) ~[seatunnel-starter.jar:2.3.6] at org.apache.seatunnel.engine.server.rest.RestHttpPostCommandProcessor.handle(RestHttpPostCommandProcessor.java:60) ~[seatunnel-starter.jar:2.3.6] at com.hazelcast.internal.ascii.TextCommandServiceImpl$CommandExecutor.run(TextCommandServiceImpl.java:402) ~[seatunnel-starter.jar:2.3.6] at com.hazelcast.internal.util.executor.CachedExecutorServiceDelegate$Worker.run(CachedExecutorServiceDelegate.java:217) ~[seatunnel-starter.jar:2.3.6] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) ~[?:1.8.0_212] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) ~[?:1.8.0_212] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_212] at com.hazelcast.internal.util.executor.HazelcastManagedThread.executeRun(HazelcastManagedThread.java:76) ~[seatunnel-starter.jar:2.3.6] at com.hazelcast.internal.util.executor.HazelcastManagedThread.run(HazelcastManagedThread.java:102) ~[seatunnel-starter.jar:2.3.6] Caused by: java.lang.OutOfMemoryError: Metaspace ``` ### Zeta or Flink or Spark Version Zeta ### Java or Scala Version 1.8 ### Screenshots _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
