catap / jaql

Jaql is a query language designed for Javascript Object Notation (JSON), a data format that has become popular because of its simplicity and modeling flexibility. Jaql is primarily used to analyze large-scale semi-structured data. Core features include user extensibility and parallelism. In addition to modeling semi-structured data, JSON simplifies extensibility. Hadoop's Map-Reduce is used for parallelism.

JAQL Windows 7 #75

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I have tried to get Jaql working on Windows 7 but failed.

The error is: Could not find the main class: JaqlShell. Programm will exit.

Is there anybody who tested Jaql on Windows 7 already and can confirm that
it works?

Thank you,

Stefan George

I haven't had any problems with it on Windows 7; I had to have cygwin installed 
for some commands to work fine. Make sure your classpath looks good.

Hi all, I'm having the same issue. I'm using Windows 7, Java 1.7, and Cygwin 
1.7.12-1. This is the error I'm getting:

from inside the jaql-0.5.1 dir...
$ ./bin/jaqlshell

I also downloaded Hadoop, but I'm not sure, if I just want to simply run the 
jaql shell, what type of additional setup for that, if any, is needed to get 
the shell working.

Any help would be appreciated! Thanks!
