Caleb William Rackliffe commented on CASSANDRA-11062: ----------------------------------------------------- I've submitted a little patch that configures {{BatchlogManager}} to stop executing delayed tasks on shutdown. > BatchlogManager May Attempt to Flush Hints After HintsService is Shutdown > ------------------------------------------------------------------------- > > Key: CASSANDRA-11062 > URL: https://issues.apache.org/jira/browse/CASSANDRA-11062 > Project: Cassandra > Issue Type: Bug > Reporter: Caleb William Rackliffe > Priority: Minor > Fix For: 3.0.x > > Attachments: 11062-3.0.txt > > > {{ScheduledThreadPoolExecutor}}'s default behavior is to keep running delayed > tasks after shutdown, so I think that means {{BatchlogManager}} is trying to > call {{replayFailedBatches()}} after drain has instructed both it and the > {{HintsService}} to shut down. When this happens, we get an exception when > that tries to submit a task to the executor in {{HintsWriteExecutor}}: > {noformat} > ERROR [BatchlogTasks:1] 2016-01-22 17:01:38,936 CassandraDaemon.java:195 - > Exception in thread Thread[BatchlogTasks:1,5,main] > java.util.concurrent.RejectedExecutionException: ThreadPoolExecutor has shut > down > at > org.apache.cassandra.concurrent.DebuggableThreadPoolExecutor$1.rejectedExecution(DebuggableThreadPoolExecutor.java:61) > ~[cassandra-all-3.0.1.816.jar:3.0.1.816] > at > java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:823) > [na:1.8.0_65] > at > java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1369) > [na:1.8.0_65] > at > org.apache.cassandra.concurrent.DebuggableThreadPoolExecutor.execute(DebuggableThreadPoolExecutor.java:165) > ~[cassandra-all-3.0.1.816.jar:3.0.1.816] > at > java.util.concurrent.AbstractExecutorService.submit(AbstractExecutorService.java:112) > ~[na:1.8.0_65] > at > org.apache.cassandra.hints.HintsWriteExecutor.flushBufferPool(HintsWriteExecutor.java:89) > ~[cassandra-all-3.0.1.816.jar:3.0.1.816] > at > org.apache.cassandra.hints.HintsService.flushAndFsyncBlockingly(HintsService.java:177) > ~[cassandra-all-3.0.1.816.jar:3.0.1.816] > at > org.apache.cassandra.batchlog.BatchlogManager.processBatchlogEntries(BatchlogManager.java:259) > ~[cassandra-all-3.0.1.816.jar:3.0.1.816] > at > org.apache.cassandra.batchlog.BatchlogManager.replayFailedBatches(BatchlogManager.java:200) > ~[cassandra-all-3.0.1.816.jar:3.0.1.816] > at > org.apache.cassandra.concurrent.DebuggableScheduledThreadPoolExecutor$UncomplainingRunnable.run(DebuggableScheduledThreadPoolExecutor.java:118) > ~[cassandra-all-3.0.1.816.jar:3.0.1.816] > at > java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) > [na:1.8.0_65] > at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) > [na:1.8.0_65] > at > java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) > [na:1.8.0_65] > at > java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) > [na:1.8.0_65] > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > [na:1.8.0_65] > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > [na:1.8.0_65] > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
