I have installed hunk 6.1.3 onto a Centos 6 Linux host and connected it to a Centos 6 Linux based CDH5 Hadoop cluster.
I have installed hunk under /usr/local/hunk and set up my configuration files to pull csv based data off of hdfs.
Hunk is running from the host hc2nn and I can start it as login at http://hc2nn:8000. I can run searches via
and I can select columns to display, create reports and dashboards. What I want to do though is create a report
from the search pane that shows minimum co2 emmissions for a particular manufacturer and model. I would then like
to limit the output to the top 20 minimum values.
Please excuse the mistakes but I understand that I can do something like this
index=cdh5_vindex manufacturer model c02_g_km | stats min(c02_g_km) as minco2 | table manufacturer model minco2
I know that this isnt the correct format but I wondered whether someone could advise the correct approach. I can create
single column reports and dashboards but I would like to create something a little more complicated.
