一、异常现象
kylin安装完，启动后，控制正常，kylin后台也能正常访问。但是去看kylin的日志，却发现报错了：
SEVERE: Failed to load keystore type JKS with path conf/.keystore due to /developer/apache-kylin-2.3.0-bin/tomcat/conf/.keystore (No such file or directory) java.io.FileNotFoundException: /developer/apache-kylin-2.3.0-bin/tomcat/conf/.keystore (No such file or directory) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(FileInputStream.java:146) at java.io.FileInputStream.<init>(FileInputStream.java:101) at sun.net.www.protocol.file.FileURLConnection.connect(FileURLConnection.java:90) at sun.net.www.protocol.file.FileURLConnection.getInputStream(FileURLConnection.java:188) at java.net.URL.openStream(URL.java:1041) at org.apache.tomcat.util.file.ConfigFileLoader.getInputStream(ConfigFileLoader.java:100) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.getStore(JSSESocketFactory.java:470) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.getKeystore(JSSESocketFactory.java:381) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.getKeyManagers(JSSESocketFactory.java:634) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.getKeyManagers(JSSESocketFactory.java:574) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.init(JSSESocketFactory.java:519) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.createSocket(JSSESocketFactory.java:255) at org.apache.tomcat.util.net.JIoEndpoint.bind(JIoEndpoint.java:400) at org.apache.tomcat.util.net.AbstractEndpoint.init(AbstractEndpoint.java:728) at org.apache.coyote.AbstractProtocol.init(AbstractProtocol.java:452) at org.apache.coyote.http11.AbstractHttp11JsseProtocol.init(AbstractHttp11JsseProtocol.java:119) at org.apache.catalina.connector.Connector.initInternal(Connector.java:978) at org.apache.catalina.util.LifecycleBase.init(LifecycleBase.java:102) at org.apache.catalina.core.StandardService.initInternal(StandardService.java:560) at org.apache.catalina.util.LifecycleBase.init(LifecycleBase.java:102) at org.apache.catalina.core.StandardServer.initInternal(StandardServer.java:840) at org.apache.catalina.util.LifecycleBase.init(LifecycleBase.java:102) at org.apache.catalina.startup.Catalina.load(Catalina.java:654) at org.apache.catalina.startup.Catalina.start(Catalina.java:693) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:294) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:428) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.hadoop.util.RunJar.main(RunJar.java:212) Mar 27, 2018 11:02:28 AM org.apache.coyote.AbstractProtocol init SEVERE: Failed to initialize end point associated with ProtocolHandler ["http-bio-7443"]
二、异常原因
因为没有HTTPS的证书，所以导致异常
三、异常解决
去掉tomcat下的https
在kylin内置tomcat的server.xml中里边有个对https的支持没启用的话 注释掉
