Hadoop is a Java implementation of Google MapReduce. MapReduce is a simplified distributed programming model that allows programs to be distributed automatically to a large cluster of ordinary machines. Just as Java programmers can do without memory leaks, MapReduce's run-time system solves the distribution details of input data, executes scheduling across machine clusters, handles machine failures, and manages communication requests between machines. Such a pattern allows programmers to not need ...

MySQL provides standard SQL pattern matching and a format based on pattern matching of extended regular expressions like Unix utilities such as vi, grep and sed. Standard SQL Pattern Matching SQL pattern matching allows you to match any single character with "_" and "%" with any number of characters (including zero characters). In MySQL, the default SQL mode is case-insensitive. Here are some examples. Note that you can not use = or! = While you are using SQL mode, and use LIKE or NOT LIKE to compare operators ...

What is Hadoop? Reference 　　Hadoop is an open source framework for writing and running distributed applications to handle large-scale data, designed for offline and large-scale data analysis, and is not suitable for online transaction processing patterns that randomly read and write to several records. Hadoop=hdfs (file system, data storage technology related) + Mapreduce (processing), Hadoop data source can be any form, in the processing of semi-structured and unstructured data and relational database with better performance, with more flexibility ...
