So, download it, install pre-requisites, build. I have built it for us as an rpm, you essay can check out the spec file here (it depends on some other packages from that repo, but you should get the idea and should be able to modify the script to build on vanilla redhat. Another option would be to take a look at Clouderas gpl extras repository and their lzo packages and documentation. After you have built and installed your lzo libraries, you should be able to use them with hbase without any additional configuration. To test hbase support for lzo compression you could use the following command: hbase mpressionTest file tmp/testfile lzo 13/06/13 04:43:14 warn nfiguration: b is deprecated.

To make sure hive map-reduce jobs would be able to read/write json tables, we needed to copy our jar file to /usr/lib/hadoop/lib directory on all task tracker servers in the cluster (the same rpm does that). And last, really important step: to make sure your TaskTracker servers know about the new jar, you need to restart your tasktracker services (we use Cloudera manager, so that was just a few mouse clicks ;-). And this is it for today. Mysql monitoring With Cacti Using Percona monitoring Plugins (1-minute resolution) 26 Jun2013, today, just like many times before, i needed to configure a monitoring server for mysql using. Cacti and awesome, percona monitoring Templates.
The only difference was that this time i wanted to get it to run with 1 min resolution (using ganglia and graphite, both with 10 sec resolution, for all the rest of our monitoring in Swiftype really spoiled me!). And thats where the usual pain in the ass Cacti configuration gets really amplified by the million things you need to change to make it work. So, this is a short checklist post for those who need to configure a cacti server with 1 minute resolution and setup Percona monitoring Plugins. Read the rest of this entry adding lzo support to Cloudera hadoop Distribution.3 13 Jun2013 Just a short note to myself and others who need to add lzo support for cdh.3. First of all, you need to build hadoop-lzo. Since cdh.3 uses hadoop.0, most of the forks of hadoop-lzo project fail to compile against new libraries. After some digging ive found the original twitter hadoop-lzo branch to be the most maintained and it works perfectly with hadoop.0.

To help us improve our infrastructure we are looking both for senior operations engineers and for more junior techops people that we could help grow and develop within the company. Both positions pelleas could be either remote or we could assist you with relocation to san Francisco if you want to work in our office. If you are interested, you can take a look at an old, but still pretty relevant post I wrote many years ago on what I believe an ops candidate should know. And, of course, if you have any questions regarding these positions in Swiftype, please email me at or use any other means for contacting me and I will try to get back to you as soon as possible. If you know someone who may be a great fit for these positions, please let them know! Adding Custom hive serde and udf libraries to Cloudera hadoop.3 26 Jul2013, yet another small note about Cloudera hadoop Distribution.3. This time i needed to deploy some custom jar files to our hive cluster so that we wouldnt need to do add jar commands in every hive job (especially useful when using hiveserver api). Here is the process of adding a custom Serde or a udf jar to your Cloudera hadoop cluster: First, we have built our json serde and got a json-serde-1.1.6.jar file. To make this file available to hive cli tools, we need to copy it to /usr/lib/hive/lib on every server in the cluster (I have prepared an rpm package to do just that).
Recently, one of the candidates asked me to share my lists with him and I thought this information could be valuable to other people so i have decided to share it here on my blog. Read the rest of this entry. Join me at Swiftype! 18 Sep2013, as you may have heard, last January i have joined. Swiftype an early stage startup focused on changing local site search for the better. It has been a blast for the past 8 months, we have done a lot of interesting things to make our infrastructure more stable and performant, immensely increased visibility into our performance metrics, developed a strong foundation for the future growth of the company. Now we are looking to expand our team with great developers and technical operations people to push our infrastructure and the product even further. Since i have joined Swiftype, i have been mainly focused on improving the infrastructure through better automation and monitoring, and worked on our backend code. Now i am looking for a few good operations engineers to join my team to work on a few key projects like building a new multi-datacenter infrastructure, creating a new data storage for our documents data, business improving high-availability of our core services and much more.

Interesting Resources for Technical Operations Engineers 23 Sep2013, as a leader of a technical operations team i often have to work on technical operations engineer hiring. This process involves a lot of interviews with candidates and during those interviews along with many challenging practical questions I really love to ask questions like what are the most important resources you think an Operations Engineer should follow?, What books in your opinion are. Or Who are your personal heroes in it community? Those questions often give me a lot of information about candidates, their experience, who they are looking up to in the community, what they are interested in, and if they are actively working on improving their professional level.
We'll then deploy linux compute instances and you'll see how to connect your client machine to linux hosts and configure your systems to run Hadoop. Finally, you'll install Hadoop, download data, and examine how to run a query. This video series will go beyond just Hadoop; it will cover everything you need to get your own clusters up and running. You will learn how to make network configuration changes as well as modify linux services. After you've installed Hadoop, we'll then go over installing hue—hadoop's. Using hue, you will learn how to download data to your Hadoop clusters, move it to hdfs, and finally query that data with hive. Learn everything you need to deploy hadoop clusters to the Cloud through these videos. You'll grasp all you need to know about handling large data sets over multiple nodes.

Publisher: Packt Publishing, release date: may 2014, duration: 2 hours 33 minutes, deploy multi-node hadoop clusters to harness the Cloud for storage and large-scale data essays processing. About This Video, familiarize yourself with Hadoop and its services, and how to configure them. Deploy compute instances and set up a three-node hadoop cluster on Amazon. Set up a linux installation optimized for Hadoop. In Detail, hadoop is an Apache top-level project that allows the distributed processing of large data sets across clusters of computers using simple programming models. It allows you to deliver a highly available service on top of a cluster of computers, each of which may be prone to failures. While big Data and Hadoop have seen a massive surge in popularity over the last few years, many companies still struggle with trying to set up their own computing clusters. This video series will turn you from a faltering first-timer into a hadoop pro through clear, concise descriptions that are easy to follow. We'll begin this course with an overview of Amazon's cloud service and its use.
