無法啟動SnappyData Server：嘗試連接到分布式系統超時

Question

我正在嘗試在具有1個定位器，1個線索和3個數據服務器的多個節點上設置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

CONF /線索：

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

CONF /服務器：

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啟動集群。 定位器和線索成功啟動，因為它在同一節點（snappydata1）上，但是數據服務器無法啟動並出現以下錯誤：

所有實例都可以執行無密碼的SSH，並且所有端口均已打開端口80、5050、10334、1527-30。

如果配置有任何錯誤或缺失，請告訴我。

謝謝。

在AWS安全組中打開某些端口后，我能夠成功設置集群。 我遵循AWS腳本來設置SnappyData，並觀察到需要在安全組中打開更多端口以進行檢測信號等。
