(To) hadoop Ecosystem

1 is the hadoop ecosystem. In general, it is the hadoop core module and derivative sub-projects.

Figure 1 hadoop ecosystem Diagram

The figure shows that the hadoop ecosystem includes the following members:

① Various browsers generate massive web data;

② The nutch project is an open-source project that quickly searches for massive web pages.

③ HDFS, hadoop Distributed File System, and big data storage system;

④ Data analysis and visualization tools;

⑤ Mapreduce, big data processing system;

⑥ Unstructured data collection and processing tools (FUSE, WebDAV, chukwa, flume, scribe );

7. Interaction tools between structured data and HDFS (hiho and sqoop );

Explain diverse mapreduce program control tools (pig, hive, jaql );

Intelliicus (Drilldown );

Workflow management tools (oozie, cascading );

? Hadoop ecosystem supervision tools (hue, karmascript, eclipse plugin, cacti, ganglia );

? Data serialization processing and task scheduling tools (Avro, Zookeeper );

? Services built on the hadoop upper layer (mahout, elastic map reduce );

? Online transaction processing storage system (hbase ).

The entire hadoop ecosystem involves big data collection, big data storage, big data processing, big data analysis, and big data applications, so as to truly find and apply the value of big data. (3) and (5) are the core modules of hadoop, which crack the difficulties of big data storage and processing.
