Kylin下构建Cube第一步出错：shell-init: error retrieving current directory

问题背景：
生产环境部署的Kylin-2.1，官方发布的最新安装包并不支持更改hbase存储的namespace，修改源码后重新打包部署过程中，build cube第一步出错

大概错误信息是：

OS command error exit with 5 – hive -e "USE default;

Kylin之前是没有问题的，构建了很多cube都没有问题，即便是出错按理讲也不会出现在第一步，第一步的动作是创建一个宽表，放到hive作为临时表。
解决思路：
第一感觉是权限问题，修改了sh脚本的执行权限，修改了hdfs上 kylin 工作目录的权限后，问题仍然存在。
重新找原因，其中有报工作目录的问题，看上去是本地目录并不是Hdfs上的目录，这才想起可能是上次重新部署Kylin的时候把旧版本的直接删除 ，但并没有停掉进程。

ps aux | grep kylin

查看进程查然有两个Kylin进程在跑，于是Kill掉旧的进程

突然想起之前有人误删了kylin的文件夹，所以去查看了一下，果然某一台机器下面存在两个kylin进程。kill 后重启就好了。

猜测的原因是原进程的安装目录已经不存在了，并行着两个Kylin
进程产生冲突。
