config.json配置优化


如果存储引擎或RPC组件是使用自定义组件,忽略以下hbase/hadoop/ice相关配置即可!


config.json包括XL-LightHouse自身配置参数和其依赖组件的配置参数。为了方便起见,将各组件常用配置参数统一放在config.json文件中。

如需进行相关优化,请修改操作节点的config.json文件,执行重启操作(restart-all.sh)即可!

1. 各组件内存初始占用比例

组件 进程最大内存占比 主要进程
HBase 20% hbase.regionserver.HRegionServer
Redis 10% /bin/redis-server
LightHouse-Tasks 17% executor.YarnCoarseGrainedExecutorBackend
LightHouse-ICE 10% IceBox.Server
Hadoop 8% DataNode、NodeManager
Kafka 2%~3% Kafka
Zookeeper 1%~2% quorum.QuorumPeerMain

2. 整体优化建议

  • 1、各组件最大内存总共占用节点内存的70%以内,集群运行时内存使用率在60~70%之间为宜;
  • 2、一般来说集群的内存资源优先分配原则为:HBase > LightHouse-Tasks 、 Reids > 其他组件进程,所指的HBase进程是指RegionServer进程。
  • 3、LightHouse-Tasks单进程内存上限配置3000M即可(除非Spark任务页面出现GC耗时标红则可适当增加少许内存),对应配置参数为:tasks_executor_memory。通过调整executors数量调整任务并行度,对应参数:tasks_num_executors,该数量配置取决于集群有多少内存资源可以分配以及当前并行度是否满足使用,初始配置时可参考以下公式: Executors数量配置为:((单节点内存 10%)/单进程内存) (集群节点数量 - 1)。 比如以三台128G内存的节点配置为例,executor数量为: ((128000 10%)/单进程内存) (集群节点数量 - 1) = 8或9
  • 4、一般来说除了HBase和Redis外,其他进程的内存都有配置上限,进程只要GC正常即可,配置过多不会对整体性能有提升,反而会浪费资源。
  • 5、redis的max_memory参数将会影响bitcount相关计算,如果bitcount计算较多建议适当增加该参数值!
