What is IPC client in Hive? What does it do?

[#1]

Hello,

As I mentioned in the title of this question, I wonder what is the IPC client in Hive, and what does it do.

If anyone happens to know, any help will be very thankful.

Thank you.

IPC is a generic concept. It's not particular to Hive. In fact several hadoop service communicate this way.

https://wiki.apache.org/hadoop/ipc

Using IPC, clients can connect to Server components at a certain port and invoke methods exposed by a server.

See properties related to ipc.client here : https://hadoop.apache.org/docs/r2.8.0/hadoop-project-dist/hadoop-common/core-default.xml
