问题背景
笔者近段什么由于好奇开始研究Apache Kylin,在环境安装的过程中遇到了很多诡异问题，这是其中的一个，记录下来分享给给位；如果你也同样遇到，希望对你有所帮助。
环境依赖
- Hadoop2.7.3
- HBase1.2.3
- Hive 2.1.1
- Kylin 1.6.0-HBase1.x
问题描述
配置好各种环境变量后，kylin正常启动；随后配置好model和cube，开始进行数据的build过程；发现程序运行后出现FileNotFoundException的异常
java.io.FileNotFoundException: File does not exist: hdfs://polaris-1:8020/tmp/hadoop-root/mapred/staging/root1659475561/.staging/job_local1659475561_0004/libjars/hive-metastore-2.1.1.jar

出现如上错误，很郁闷，上网查了很多后依然没有找到问题的原因，于是下载代码自己研究；上述异常的原因是找不到hive-metastore的包；由于依赖的是Hadoop2.7.3 ，按照堆栈查看代码发现找不到对应的行；此时就怀疑是由于版本依赖错误导致；通过jinfo命令查看kylin依赖的classpath

果然，kylin依赖了hbase classpath的内容，其中包含了hadoop2.5.1的相关包，去掉相关的依赖；问题得到解决。
