Impala-shell 启动异常 - Python版本为3.x 启动脚本为2.x

启动 Impala-shell 报错如下 

[root@xxx ~]# impala-shellFile "/opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/bin/../lib/impala-shell/impala_shell.py", line 222print '\tNo options available.'^ SyntaxError: Missing parentheses in call to 'print'

发现语法不支持，2.x 与3.x 语法有很大区别，我们这台机器python 版本为 3.x，寻找Impala-shell 执行脚本

发现在目录 /opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/bin 下

vim 查看脚本，发现最后一行有执行 python xxx

PYTHONPATH="${EGG_PATH}${SHELL_HOME}/gen-py:${SHELL_HOME}/lib:${PYTHONPATH}" \exec python ${SHELL_HOME}/impala_shell.py "$@"

因为python默认是3.x版本，把 python修改成python2 ，重新运行,ok
