无法启动SnappyData服务器:尝试连接到分布式系统超时

Question

我正在尝试在具有1个定位器、1个引线和3个数据服务器的多个节点上设置SnappyData集群。

集群配置: conf/locators：

snappydata1 -peer-discovery-port=10334 -dir=/opt/snappydata/snappydata-1.0.2.1-bin/work/locator -heap-size=8192m

会议/销售线索：

snappydata1 -dir=/opt/snappydata/snappydata-1.0.2.1-bin/work/lead -heap-size=8192m -member-timeout=12000

conf/servers：

snappydata2 -dir=/opt/snappydata/snappydata-1.0.2.1-bin/work/server -heap-size=24g -locators=snappydata1:10334
snappydata3 -dir=/opt/snappydata/snappydata-1.0.2.1-bin/work/server -heap-size=24g -locators=snappydata1:10334

我正在使用./sbin/snappy-start-all.sh启动集群。定位器和lead成功启动，因为它们在同一节点(Snappydata1)上，但数据服务器无法启动，并出现以下错误：

> ./sbin/snappy-start-all.sh

所有实例都能够执行无密码SSH，而且端口80、5050、10334、1527-30也为所有实例开放。

如果配置中有任何错误或丢失，请让我知道。

谢谢。

在打开AWS安全组中的某些端口后，我能够成功地设置集群。我跟踪了AWS Scripts to setup SnappyData，观察到它需要在安全组中打开更多的端口，用于心跳等。
