Another advantage of the EMR is seamless integration with Amazon S3. Essentially, when running a EMR job you specify where to read data from and save results to on S3. The only limitati

Hadoop I recently joined Cloudera, and before that, I have been working on computational biology/genomics for almost 10 years. My analytical work is mainly done using the Python language and its great scientific computing stack. But most of the Apache Hadoop ecosystem is implemented in Java and is prepared for Java, which makes me very annoyed. So, my first priority became the search for some of the

Python. In this article, I will write down some of my personal views on these frameworks that are irrelevant to science. These frameworks include: Hadoop stream Mrjob Dumbo Hadoopy Pydoop Others In the end, in my opinion, Hadoop's data stream (streaming) is the fastest and most transparent option and most suitable for text processing. Mrjob is best suited for quick work on Amazon EMR, but with sign

Recently, I joined Cloudera, and before that, I had been working on computational biology/genomics for almost 10 years. My analytical work is mainly done using the Python language and its great scientific stack of calculations. But I'm annoyed that most of the Apache Hadoop ecosystems are implemented in Java and are prepared for Java. So my top priority is to look for some Hadoop frameworks that Python can

Hadoop Foundation----Hadoop Combat (vi)-----HADOOP management Tools---Cloudera Manager---CDH introduction We have already learned about CDH in the last article, we will install CDH5.8 for the following study. CDH5.8 is now a relatively new version of Hadoop with more than hadoop2.0, and it already contains a number of

Chapter 2 mapreduce IntroductionAn ideal part size is usually the size of an HDFS block. The execution node of the map task and the storage node of the input data are the same node, and the hadoop performance is optimal (Data Locality optimization, avoid data transmission over the network ). Mapreduce Process summary: reads a row of data from a file, map function processing, Return key-value pairs; the system sorts the map results. If there are multi
