安裝cdh5.0執行impala-shell命令報impala_shell.py文件找不到

一 問題描述

    採用package包方式安裝cdh時, 安裝程序會將impala-shell目錄下的全部文件複製到/usr/lib/impala-shell下面, 但採用parcels安裝時,安裝程序並不會建立/usr/lib/impala-shell目錄,也不會複製相應的文件, 因此安裝好CDH後,執行impala-shell會報impala_shell.py找不到.

[root@kthdpp01 hadoop]# impala-shell 
ls: 沒法訪問/usr/lib/impala-shell/ext-py/*.egg: 沒有那個文件或目錄
python: can't open file '/usr/lib/impala-shell/impala_shell.py': [Errno 2] No such file or directory

二 解決方案

    mkdir -p /usr/lib/impala-shell/

    /opt/cloudera/parcels/CDH/lib/impala-shell

    cp -r * /usr/lib/impala-shell/

運行impala-shell命令,能夠正常的執行查詢
