install cloudera impala shell on mac os x and connect to impala cluster

Question

We have impala server on prod and I need connect to it with impala shell from my local macbook w/ mac os x (10.8).

I downloaded Impala-cdh5.1.0-release.tar.gz, unarchived it, tried buildall.sh which failed: .../bin/impala-config.sh: line 123: nproc: command not found

Trying impala-shell directly also fails:

$ shell/impala-shell 
ls: /Users/.../Impala-cdh5.1.0-release/shell/ext-py/*.egg: No such file or directory
 Traceback (most recent call last):
 File "/Users/.../Impala-cdh5.1.0-release/shell/impala_shell.py", line 20, in <module> 
 import prettytable
ImportError: No module named prettytable

I have jdk installed and JAVA_HOME is set. Cloudera manager seems doesn't support mac os, does it?

Based on your limited error message:

.../bin/impala-config.sh: line 123: nproc: command not found

I'd say that no, this package from cloudera doesnt support OSX. nproc is a linux command, and anything that references it isn't going to work on OSX.

If you could provide more information - such as where you downloaded it, or what it is, for those of us who aren't cloudera customers, we might be able to devise workarounds.

Or, contact cloudera support and complain about the lack of OSX support?

Your second error message looks like python, not java - and you provide no context around it....
