This is true of many other variable types, such as short <-> int16,long <->int64.

Working with text is a common usage of the MapReduce process, because text processing is relatively complex and processor-intensive processing. The basic word count is often used to demonstrate Haddoop's ability to handle large amounts of text and basic summary content. To get the number of words, split the text from an input file (using a basic string tokenizer) for each word that contains the count, and use a Reduce to count each word. For example, from the phrase the quick bro ...

Using Lzo compression algorithms in Hadoop reduces the size of the data and the disk read and write time of the data, and Lzo is based on block chunking so that he allows the data to be decomposed into chunk, which is handled in parallel by Hadoop. 　　This feature allows Lzo to become a very handy compression format for Hadoop. Lzo itself is not splitable, so when the data is in text format, the data compressed using Lzo as the job input is a file as a map. But s ...
