Visualizing Pig Queries Through Lipstick

-

Quite often while working with Pig you would have reached a situation wherein you found that your Pig scripts have reached such a level of complexity that the flow of execution, and it’s relation to the MapReduce jobs being executed, has become difficult to visualize. And this eventually ends up with the need of additional efforts required to develop, maintain, debug, and monitor the execution of scripts.

But not anymore. Thankfully Netflix has developed a tool that enables developers to visualize and monitor the execution of their data flows at a logical level, and they call it Lipstick. As an plementation of PigProgressNotificationListener, Lipstick piggybacks on top of all Pig scripts executed in our environment notifying a Lipstick server of job executions and periodically reporting progress as the script executes.

Lipstick has got some really cool features. For instance once you are at the Lipstick main page you can see all the Pig jobs that are currently running or have run. The following things are displayed for each job:
– User
– Job
– Start Time
– Heartbeat Time (last time a heartbeat was sent)
– Progress
             – Blue (running)
             – Green (complete)
             – Red (failed)
             – Orange (terminated)
  •  Clicking on the header (User, Job, Start Time, etc.) for a column will sort by the column (asc/desc).
  • Search by username or job name.
  • Filter jobs by progress.
  • Pagination controls (next page, show X jobs per page, etc).

Along with this there is a whole bunch of other cool stuff that Lipstick offers. You can find more on Lipstick user guide.

For a detailed overview you can visit their official blog section. And if you can't wait anymore and want to give it a try straight away, you can directly go to their repository.

Fun with HBase shell

-
Image
HBase shell is great, specially while getting yourself familiar with HBase. It provides lots of useful shell commands using which you can perform trivial tasks like creating tables, putting some test data into it, scanning the whole table, fetching data from a specific row etc etc. Executing  help  on HBase shell will give you the list of all the HBase shell commands. If you need help on a specific command, type help "command" . For example, help "get" will give you a detailed explanation of the get command. But this post is not about the above said stuff. We will try to do something fun here. Something which is available, but less known. So, get ready, start your HBase daemons, open HBase shell and get your hands dirty. For those of us who are unaware, HBase shell is based on  JRuby , the Java Virtual Machine-based implementation of Ruby. More specifically, it uses the  Interactive Ruby Shell (IRB) , which is used to enter Ruby commands and get an immedia

BETWEEN OPERATOR IN HIVE

-
Hive is a wonderful tool for those who like to perform batch operations to process their large amounts of data residing on a Hadoop cluster and who are comparatively new to the NOSQL world. Not only it provides us warehousing capabilities on top of a Hadoop cluster, but also a superb SQL like interface which makes it very easy to use and makes our task execution more familiar. But, one thing which newbies like me always wanted to have is the support of BETWEEN operator in Hive. Since the release of version 0.9.0  earlier  this year, Hive provides us some new and very useful features. BETWEEN operator is one among those.

HOW TO SETUP AND CONFIGURE 'ssh' ON LINUX (UBUNTU)

-
SSH (Secure Shell) is a network protocol  secure data communication, remote shell services or command execution and other secure network services between two networked computers that it connects via a secure channel  over an insecure network. The ssh server runs on a machine (server) and ssh client runs on another machine (client). ssh has 2 main components : 1- ssh : T he command we use to connect to remote machines - the client.  2-  sshd : T he daemon that is running on the  server  and allows clients to connect to the server. ssh is pre-enabled on Linux, but in order to start sshd daemon , we need to install ssh first. Use this command to do that : $ sudo apt-get install ssh This will install ssh on your machine. In order to check if ssh is setup properly do this : $ which ssh It will throw this line on your terminal /usr/bin/ssh $ which sshd It will throw this line on your terminal /usr/bin/sshd SSH uses  public-key cryptography  to  authenticate  the remote co
