Description
This surfaced after SOLR-16187 which should tell us why some builds were just timing out in the past. Now we have a stacktrace of where the pool got stuck.
Build: https://jenkins.thetaphi.de/job/Solr-main-Linux/7070/ Java: 64bit/jdk-11.0.15 -XX:+UseCompressedOops -XX:+UseSerialGC 1 tests failed. FAILED: org.apache.solr.hdfs.update.TestHdfsUpdateLog.classMethod Error Message: java.lang.RuntimeException: Timeout waiting for pool org.apache.solr.common.util.ExecutorUtil$MDCAwareThreadPoolExecutor@12bfe088[Shutting down, pool size = 1, active threads = 1, queued tasks = 0, completed tasks = 0] to shutdown. Stack Trace: java.lang.RuntimeException: Timeout waiting for pool org.apache.solr.common.util.ExecutorUtil$MDCAwareThreadPoolExecutor@12bfe088[Shutting down, pool size = 1, active threads = 1, queued tasks = 0, completed tasks = 0] to shutdown. at __randomizedtesting.SeedInfo.seed([C45530E56E50859A]:0) at org.apache.solr.common.util.ExecutorUtil.awaitTermination(ExecutorUtil.java:112) at org.apache.solr.common.util.ExecutorUtil.awaitTermination(ExecutorUtil.java:99) at org.apache.solr.common.util.ExecutorUtil.shutdownAndAwaitTermination(ExecutorUtil.java:89) at org.apache.solr.core.SolrCores.close(SolrCores.java:149) at org.apache.solr.core.CoreContainer.shutdown(CoreContainer.java:1188) at org.apache.solr.util.TestHarness.close(TestHarness.java:397) at org.apache.solr.SolrTestCaseJ4.deleteCore(SolrTestCaseJ4.java:942) at org.apache.solr.hdfs.update.TestHdfsUpdateLog.afterClass(TestHdfsUpdateLog.java:75)
TestHdfsUpdateLog, TestRecoveryHdfs, and TestRandomCollapseQParserPlugin were trying to call deleteCore which doesn't shutdown the test case correctly sometimes. Instead call SolrTestCaseJ4.teardownTestCases which does the cleanup. It is ok to call SolrTestCaseJ4.teardownTestCases twice.
