You may want to insert a lot of data into Redis. This would be easier to insert a lot of data into Redis using Linux commands. Let's say we have a comma separated values in a file.data.csv: key1,1200key2,5000key35,12345key12,4500With the following command, you can load all the data into Redis. But you should start the Redis server first. You can change ...

Recently we used Redis server on Ubuntu 14.04. And I just thought about writing a blog post to show how to build Redis on Ubuntu server or desktop editions. First of all, you have to go to the Redis site and download the Redis source code. Redis siteCopy the download link from Redis site. Currently, download link looks like this ...

We recently purchased a Cisco switch for our Hadoop cluster. So I wanted to setup Cisco switch. But first of all I want to configure ssh and disable telnet. Lets see how we can do that. Connect to the switch using telnet or using console port. (You should enable telnet and give a password from express setup.) enableconfigure terminalhostname <switchname>ip ...

I haven't used encryption on hard disk drives or pen drives ever. But recently I got a requirement to encrypt some portables disks. And there are some limitations also. After encrypting you would not be able to use that drive on Windows Operating System. You are going to limit to the ext4 file system as well.First, you have to install ...

We have been using d3js to visualize things on maps. And after struggling with topojson application my boss found a way to convert Sri Lanka Shapefile (.shp) to topojson format. Then we wanted to use cartograms for our visualizations. I found that there was a d3js cartogram implementation. - https://github.com/shawnbot/d3-cartogram/With the help of this blog post - http://www.limn.co.za/2013/10/making-a-cartogram/, I finished ...

It's funny! You can have mapper only Hadoop MapReduce Jobs. This would be useful sometime when you need to change the structure of data. Otherwise, you can use this way when to want to filter out data. But I don't think you will need this much often.The first file is a simple mapper which really does nothing. You can change ...
