启动
$KYLIN_HOME/bin/check-env.sh
$KYLIN_HOME/bin/kylin.sh start
运行例子
$KYLIN_HOME/bin/sample.sh
默认运行在localhost：7070/kylin
ADMIN/KYLIN
在启动kylin的时候遇到了很多坑，最坑的莫过于这个
Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
报了java的runtimeException
然后恶心了好久
最后发现原因是因为
kylin在使用hive的时候要启动一个hive线程，而这个线程只能存在一个
所以，当你把hive搭好，执行hive命令跑起来以后，要用kylin了，要把之前这个hive进程停掉先。。。
