————— 2022-11-9 ————— Jason 18:05 Ladies and gentlemen, please ask a question: What causes the frequent occurrence of spark engine RequestEngineLock time out? No relevant issue was received peacewong@WDS 18:49 I need to check spark ec's log for this Jason 19:06 ec log, every time when tryLock can not go Jack 19:09 Delete the database execution information and try again Jack 19:09 Back up First Jason 19:12 What execution information do you mean? Jack 19:13 linkis_cg_manager_lock Jason 19:16 Jason 19:16 The database has no lock record peacewong@WDS 19:17 Not this lock, this should have been fixed, you can look at jstack, it should be stuck syncing. Jason 19:17 good I think it's also because I haven't typed this log Jason 19:18 How many issues are fixed? I can't find it. peacewong@WDS 19:18 I'll send it later Jason 19:18 Ok, thanks a lot peacewong@WDS 19:42 You can view the specific jstack of spark ec Jason 19:43 Ok, hold on Jason 19:51 You can look at that peacewong@WDS 19:54 This one doesn't have a line break. It's not very nice Jason 19:55 Take a look at this peacewong@WDS 20:06 It looks like this one has an exception, the executor is still executing, and the lock should not have been requested. peacewong@WDS 20:06 Jason 20:14 good Jason 18:05 各位大佬，请教个问题：spark引擎经常出现 RequestEngineLock time out 是什么原因导致的呢？ 没有收到相关的issue peacewong@WDS 18:49 这个要看看spark ec那边的日志下 Jason 19:06 ec 的日志，每次都是tryLock的时候走不动了 Jack 19:09 数据库的执行信息 删掉 再试试 Jack 19:09 先备份 Jason 19:12 你是指什么执行信息？ Jack 19:13 linkis_cg_manager_lock Jason 19:16 Jason 19:16 数据库没锁记录 peacewong@WDS 19:17 不是这个锁，这个应该已经修复了，你可以看看jstack，应该是同步卡住了。 Jason 19:17 好的。我感觉也是因为我这个日志都没打 Jason 19:18 修复的issue 是多少呀？我没找到 peacewong@WDS 19:18 晚点我发下 Jason 19:18 好的，多谢 peacewong@WDS 19:42 可以给下spark ec具体的jstack看看下 Jason 19:43 好的，稍等 Jason 19:51 可以看下 peacewong@WDS 19:54 这个没有换行，不太好看 Jason 19:55 看下这个 peacewong@WDS 20:06 看起来是这个有异常，executor还在执行，不应该被请求锁来着。 peacewong@WDS 20:06 Jason 20:14 好的 -- Best Regards ------ 康悦 ritakang GitHub：Ritakang0451 E-mail：rita0...@163.com
