ignite客戶端啟動時無法連線服務端
異常
[21:01:02,094][SEVERE][main][IgniteKernal] Failed to startmanager:GridManagerAdapter[enabled=true, name=o.a.i.i.managers.discovery.GridDiscoveryManager]class org.apache.ignite.IgniteCheckedException: Failed to start SPI: TcpDiscoverySpi[addrRslvr=null,sockTimeout=5000,ackTimeout=5000,marsh=JdkMarshaller[],reconCnt=10,maxAckTimeout=600000,forceSrvMode=false, clientReconnectDisabled=false] at org.apache.ignite.internal.managers.GridManagerAdapter.startSpi(GridManagerAdapter.java:300) at org.apache.ignite.internal.managers.discovery.GridDiscoveryManager.start(GridDiscoveryManager.java:842) at org.apache.ignite.internal.IgniteKernal.startManager(IgniteKernal.java:1786) at org.apache.ignite.internal.IgniteKernal.start(IgniteKernal.java:978) at org.apache.ignite.internal.IgnitionEx$IgniteNamedInstance.start0(IgnitionEx.java:1896) at org.apache.ignite.internal.IgnitionEx$IgniteNamedInstance.start(IgnitionEx.java:1648) at org.apache.ignite.internal.IgnitionEx.start0(IgnitionEx.java:1076) at org.apache.ignite.internal.IgnitionEx.start(IgnitionEx.java:596) at org.apache.ignite.internal.IgnitionEx.start(IgnitionEx.java:520) at org.apache.ignite.Ignition.start(Ignition.java:322)
出現這個異常的原因不只一種，不過我的原因是版本不一致，在工程的pom檔案中新增的ignite相關依賴是2.3.0版本的，但是服務端版本是1.9.0，所以連線不上。
解決方案：將服務端與ignite依賴版本保持一致。
