本地使用idea远端调试kylin代码

2019独角兽企业重金招聘Python工程师标准>>>

使用idea从git上拉取kylin的master代码

在idea命令端执行:
拉出相应版本代码
git tag

kylin-1.5.3-cdh5.7
kylin-1.5.4
kylin-1.5.4-HBase1.x
kylin-1.5.4-cdh5.7
kylin-1.5.4.1

git checkout kylin-1.5.4-HBase1.x


package org.apache.kylin.rest.controller;
@Controller
public class QueryController extends BasicController {
...
    @RequestMapping(value = "/query", method = RequestMethod.POST)
    @ResponseBody
    public SQLResponse query(@RequestBody SQLRequest sqlRequest) {
        return doQueryWithCache(sqlRequest);
    }
...
}

对return doQueryWithCache(sqlRequest); 行进行debug

配置host,port
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8787

在服务器端配置kylin/setenv.sh
export KYLIN_DEBUG_SETTINGS="-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8787"
然后重启kylin
kylin.sh stop
kylin.sh start
启动后,kylin/setenv.sh 注释掉,新的cube build会使用这个端口,导致报错

本地idea点击debug,就可以调试了.
