你好:

  我三台服务器安装了doris,1FE+2BE。每台BE服务器,装两个BE节点。目前doris运行正常。

  看日志,显示大量“(tablet scheduler|39) [TabletScheduler.removeTabletCtx():1349] 
remove the tablet 16007. because: schedule failed too many times and unable to 
find low backend”

1.执行,命令 show proc "/cluster_balance/sched_stat";得到如下返回值。

2 猜想,是不是定时任务线程数少?

  将参数 max_connection_scheduler_threads_num 从 4096 调整到 8192 能否解决该问题。

问:有没有其他解决方案

                                                 谢谢




FE 及BE 参数 如下:

enable_batch_delete_by_default=true
max_routine_load_task_num_per_be=24
max_concurrent_task_num_per_be=24

BE

base_compaction_trace_threshold=60
