Does hadoop use epoll to manage the network read/write/errors events?

[gschen <go...@yahoo.com.cn>]

Hi guys,

I am new to hadoop. And I have a question about hadoop:

does hadoop use epoll to manage all the network read/write/error events?

Any help would be much appreciated.

Thanks in advance.

Hadoop uses NIO. So, through nio, epoll/wait will be used.
