安裝cdh5.0執行impala-shell指令報impala_shell.py檔案找不到

一 問題描述

    采用package包方式安裝cdh時, 安裝程式會将impala-shell目錄下的所有檔案複制到/usr/lib/impala-shell下面, 但采用parcels安裝時,安裝程式并不會建立/usr/lib/impala-shell目錄,也不會複制相應的檔案, 是以安裝好cdh後,執行impala-shell會報impala_shell.py找不到.

[root@kthdpp01 hadoop]# impala-shell 

ls: 無法通路/usr/lib/impala-shell/ext-py/*.egg: 沒有那個檔案或目錄

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/

運作impala-shell指令,可以正常的執行查詢
