Hadoop Mr class diagram outline

The analysis framework is nothing more than a class chart. Recently, I personally drew this type of chart.

Mainly divided:

Client, jobtracker, tasktracker, taskrunner, and clild.

Some are called through RPC and some are called through shell commands.

Blocking is either wait \ nodflood, network, or queue...

In the future, the blog will analyze the functions of each part, especially the coordination of compensation mechanisms.

BTW: Report, filexxx, and log are not reflected in the figure.

This figure mainly sorts out the relationships between various types.
