一 问题描述
采用package包方式安装cdh时, 安装程序会将impala-shell目录下的所有文件复制到/usr/lib/impala-shell下面, 但采用parcels安装时,安装程序并不会创建/usr/lib/impala-shell目录,也不会复制相应的文件, 所以安装好CDH后,执行impala-shell会报impala_shell.py找不到.
[root@kthdpp01 hadoop]# impala-shell
ls: 无法访问/usr/lib/impala-shell/ext-py/*.egg: 没有那个文件或目录
python: can't open file '/usr/lib/impala-shell/impala_shell.py': [Errno 2] No such file or directory
二 解决方案
mkdir -p /usr/lib/impala-shell/
/opt/cloudera/parcels/CDH/lib/impala-shell
cp -r * /usr/lib/impala-shell/
运行impala-shell命令,可以正常的执行查询
[root@kthdpp01 impala-shell]# impala-shell
