在当前数据驱动的业务环境中,快速且高效的数据处理能力至关重要。Apache SeaTunnel以其卓越的性能和灵活性,成为数据工程师和开发者的首选工具之一。本文将介绍如何在集群环境中搭建Apache SeaTunnel 2.3.5版本的 Zeta-Server,并概述其使用方法。

编辑/etc/profile文件,添加如下配置:
export SEATUNNEL_HOME=${seatunnel install path}
export PATH=$PATH:$SEATUNNEL_HOME/bin
SeaTunnel Zeta Server的jvm配置文件路径为${SEATUNNEL_HOME}/config/jvm_options,可以在这里调整JVM相关配置。
一定要编辑的几个配置:
cluster-name SeaTunnel Engine 节点使用 cluster-name 来确定另一个节点是否与自己在同一集群中。如果两个节点之间的集群名称不同,SeaTunnel 引擎将拒绝服务请求。
网络 基于 Hazelcast, 一个 SeaTunnel Engine 集群是由运行 SeaTunnel Engine 服务器的集群成员组成的网络。 集群成员自动加入一起形成集群。这种自动加入是通过集群成员使用的各种发现机制来相互发现的。
请注意,集群形成后,集群成员之间的通信始终通过 TCP/IP 进行,无论使用的发现机制如何。 示例:
hazelcast:
cluster-name: seatunnel
network:
join:
tcp-ip:
enabled: true
member-list:
- hostname1
port:
auto-increment: false
port: 5801
properties:
hazelcast.logging.type: log4j2
seatunnel:
engine:
classloader-cache-mode: true
seatunnel:
engine:
history-job-expire-minutes: 1440
更多配置可以参考官方文档:https://seatunnel.apache.org/zh-CN/docs/2.3.5/seatunnel-engine/deployment#4-%E9%85%8D%E7%BD%AE-seatunnel-engine
SeaTunnel Client的jvm配置文件路径为${SEATUNNEL_HOME}/config/jvm_client_options,可以在这里调整JVM相关配置,在使用bin/seatunnel.sh --config xxx.conf提交任务时会启动一个java进程,可以使用此配置来控制java进程参数。

引擎客户端配置文件路径为:${SEATUNNEL_HOME}/config/hazelcast-client.yaml
cluster-name 客户端必须与 SeaTunnel Engine 具有相同的 cluster-name。否则,SeaTunnel Engine 将拒绝客户端的请求。
cluster-members 需要将所有 SeaTunnel Engine 服务器节点的地址添加到这里。示例:
hazelcast-client:
cluster-name: seatunnel
properties:
hazelcast.logging.type: log4j2
network:
cluster-members:
- hostname1:5801
${SEATUNNEL_HOME}/bin/seatunnel-cluster.sh -d
