storm基本配置

storm.local.dir: nimbus 和supervisor进程存储一些状态信息（conf或者jars）的本地路径，需要每台storm node单独创建该目录并保证该目录有正确的读写权限;
storm.log4j2.conf.dir： log4j的配置目录;
storm.zookeeper.servers: storm严重依赖zookeeper存储状态信息，要保证zookeeper的高可用，最好设置多个zk地址;
storm.zookeeper.port: 默认2181;
storm.zookeeper.root: 在zookeeper中存储的根目录，如果多个storm集群公用一个zk集群，需要修改其根目录名称即可;
storm.session.timeout: 默认20s，nimbus和supervisor和zk的session超时时间，如果log中常用sessiontimeout错误，考虑增加其值或者修改gc参数。该值并不能无限设置，zk有自己的最大session时间（默认20 ticktime）；
storm.zookeeper.connection.timeout：连接超时时间；
storm.zookeeper.retry.times: 默认5，执行zk操作重试次数；
storm.zookeeper.retry.interval: 默认1000，即间隔1s；
storm.zookeeper.retry.intervalceiling.millis: 300000 （5分钟）执行重试的时间间隔最长时间；
storm.messaging.transport：”backtype.storm.messaging.netty.Context” task之间的消息传输协议，默认使用netty传输；
storm.cluster.mode: “distributed” storm集群模式；
storm.id：运行中拓扑的id,由storm name和一个唯一随机数组成；
storm.local.mode.zmq：Local模式下是否使用ZeroMQ作消息系统，如果设置为false则使用java消息系统。默认为false；
注：Storm严重依赖zookeeper，而且zk在分布式使用中扮演了非常重要的角色。

nimbus相关设置

storm.nimbus.retry.times： 5 nimbus操作的重试次数
storm.nimbus.retry.interval.millis： 2s 重试间隔
storm.nimbus.retry.intervalceiling.millis: 60000 最大重试时间 10分钟
nimbus.seeds: [] 用于leader nimbus发现的nimbus hosts 列表，解决nimbus的单点故障问题，代替了原来的nimbus.host 配置
nimbus.thrift.port: 6627 nimbus工作的thrift端口，客户端上传jar和提交拓扑的端口（nimbus的thrift监听端口）
nimbus.thrift.threads: 64 nimbus thrift 线程数目
nimbus.thrift.max_buffer_size: 1048576 1m
nimbus.childopts: “-Xmx1024m” nimbus java 进程jvm设置
nimbus.task.timeout.secs：30 与task没有心跳时多久nimbus可以认为该task已经死掉并且可以重新分配该task
nimbus.supervisor.timeout.secs: 60 一分钟没有心跳 nimbus可以认为该supervisor已经dead，不会分配新的work
nimbus.monitor.freq.secs: 10 nimbus多久查询下supervisor心跳信息并且重新分配工作。注意当一台机子曾经挂掉，nimbus会立即采取一些操作
nimbus.reassign：当发现task失败时nimbus是否重新分配执行。默认为真，不建议修改。
nimbus.cleanup.inbox.freq.secs: 600 多久时间启动清理inbox文件的线程
nimbus.inbox.jar.expiration.secs: 3600 一个小时 jar过期时间
nimbus.code.sync.freq.secs: 300 5分钟同步一次未执行的拓扑的代码
nimbus.task.launch.secs: 120 用于task 第一次启动时的超时时间
nimbus.file.copy.expiration.secs: 600 上传下载文件超时时间
nimbus.topology.validator: “backtype.storm.nimbus.DefaultTopologyValidator” 拓扑验证，控制该拓扑是否可以执行
topology.min.replication.count: 1 当nimbus seeds中该拓扑代码的备份达到最小数目时leader nimbus才可以执行拓扑动作。
topology.max.replication.wait.time.sec: 60 当代码备份在nimbus list中达到topology.min.replication.count设置的最大等待时间，如果超时，不管有没有最小备份个数，都要执行该拓扑

supervisor相关配置

supervisor.slots.ports: 设置当台机子上可跑的worker数目，每个worker对应一个port，通常情况下多少个cpu core就设置多少个worker，类似与hadoop中nodemanager中slot的设置
supervisor.childopts: “-Xmx256m” supervisor jvm参数设置
supervisor.worker.start.timeout.secs: 120 supervisor等待worker启动的最长时间
supervisor.worker.timeout.secs: 30 worker的最长超时时间
supervisor.worker.shutdown.sleep.secs: 1秒 supervisor shutdown worker需要等待的时间
supervisor.monitor.frequency.secs: 3s检查一次worker的心跳确保是否要重启这些worker
supervisor.heartbeat.frequency.secs: 5s supervisor和nimbus心跳的频率
supervisor.enable: true supervisor是否要启动分配它的worker

worker 配置

worker.childopts: “-Xmx768m”
worker.gc.childopts: “” worker gc set 可以被topology.worker.gc.childopts.覆盖
worker.heartbeat.frequency.secs: 1 worker 和supervisor的heartbeat时间
topology.worker.receiver.thread.count: 1 每个worker设置的receiver 线程个数
task.heartbeat.frequency.secs: 3s task向nimbus发送心跳的频率
task.refresh.poll.secs: 10 多久和其他task同步连接（如果task重新分配，发往该task信息的那些task需要重练他们之间的连接）

message传递相关参数

storm.messaging.netty.server_worker_threads：1， server端接收信息的线程个数
storm.messaging.netty.client_worker_threads: 1， client端发送信息的线程个数
storm.messaging.netty.buffer_size: 5M，netty buffer大小
storm.messaging.netty.max_retries: 300 重试次数
storm.messaging.netty.max_wait_ms: 1000ms=1s 最大等待时间要大于task launchtime and worker launch time默认120s，重连间隔要大于zk的sessiontimeout 以确保worker是否已挂
storm.messaging.netty.min_wait_ms: 100
storm.messaging.netty.transfer.batch.size: 262144 如果netty 发送消息非常忙，client客户端可以batch发送消息，否则尽快的flush消息以减少延迟。

topology相关的设置，针对特定拓扑的配置

topology.enable.message.timeouts: true 保证数据完全处理；
topology.acker.executors: null 设置acker线程个数；
topology.message.timeout.secs: 30 当一个消息的处理超时多长时间多少认为该tuple处理失败；
topology.max.spout.pending: null 当spout 发送一个tuple时会将该tuple放到一个pending list，此字段控制在storm中处理的spout tuple数，可以根据超时时间以及每秒处理的消息数估算；
topology.workers: 1，Config#setNumWorkers，设置worker数，一个worker执行一个拓扑的一个子集任务，其上可以跑多个excutors，可能是多个bolt或者spout；
topology.tasks: null，top.setNumtasks，设置task数目；
topology.max.task.parallelism: null，拓扑最大线程数；

worker gc设置

topology.worker.childopts: null；
topology.worker.logwriter.childopts: “-Xmx64m”；
topology.worker.shared.thread.pool.size: 4 worker task 共享线程池大小；

worker内消息传送的参数，与disruptor相关：

topology.executor.receive.buffer.size: 1024 #batched；
topology.executor.send.buffer.size: 1024 #individual messages；
topology.transfer.buffer.size: 1024 # batched；
topology.disruptor.wait.strategy:com.lmax.disruptor.BlockingWaitStrategy 延迟和吞吐率权衡；
topology.disruptor.wait.timeout.millis: 1000 延迟和cpu使用权衡，使用长延时时会减少cpu使用，减少等待时间可以保证延时小，但cpu负载高；

其他参数配置：

topology.debug: false debug模式关闭；
topology.tick.tuple.freq.secs: null 用于定时处理逻辑的拓扑使用；
topology.spout.wait.strategy: “backtype.storm.spout.SleepSpoutWaitStrategy” 两种情形下等待1. no data 2. 达到最大pending大小；
topology.sleep.spout.wait.strategy.time.ms: 1 sleep时间；
