Which type of containers technology apache Hadoop used?

Asked 2022-Mar-20 at 14:36

Does anyone know which containers technology (Docker, LXC,....) is used in apache Hadoop, especially in (HDFS) and (Mapreduce)? I know its used container technology but I can not find which one in specific.

Out of the box, none. What YARN calls "containers", by default, are bare-metal JVM instances that are scheduled using the YARN NodeManagers.

YARN can be configured to use Docker or runC.

Docker | How to prevent having to rebuild image on code changes

Asked 2022-Feb-21 at 01:06

I started using Docker for a personal project and realized that this increases my development time to an unnacceptable amount. I would rather spin up an LXC instance if I had to rebuild images for every code change.

I heard there was a way to mount this but wasn't sure exactly how one would go about it. I also have a docker compose yaml file but I think you mount a volume or something in the Dockerfile? The goal is to have code changes not need to rebuild a container image.

Here's what I would suggest to make dev builds faster:

Bind mount code into the container

A bind mount is a directory shared between the container and the host. Here's the syntax for it:

The default path to the ansible inventory is /etc/ansible/hosts, not /etc/ansible/hosts.yml. You need to remove the file extension.

You can also set a different path to the inventory file with the -i flag when running ansible.

input password to command in golang

Asked 2021-Nov-18 at 01:50

I need to use lxd-p2c(https://github.com/lxc/lxd/tree/master/lxd-p2c) in golang code.

I try to pass password to the binary lxd-p2c built by the code above, which uses term.ReadPassword(0)(https://github.com/lxc/lxd/blob/master/lxd-p2c/utils.go#L166) to read password in Linux.

I did some search on the internet and tried following code but they just did not work.

ANSWER

Answered 2021-Nov-14 at 20:52

Checking the error in your playground displays inappropriate ioctl for device.

Searching for the error message I found this thread [1], which notes that non-terminal input is not supported for terminal.ReadPassword. My guess is that passing Stdin input this way makes it pass the input with a character device instead of with the necessary terminal device like tty or any such, making the read fail. lxd-p2c can't read the password from such an input device.

QUESTION

UTC Date Time not matching between two machines

Asked 2021-Oct-13 at 08:20

I have two projects, one written in JS and another in Python. I have a functionality that requires to calculate the current UTC time difference coming from both projects. When I test the current UTC time I notice there is always the exact difference, and I'm expecting it to be almost equal.

The time difference calculation is done in the JS project. Using a websocket, I'm getting the UTC time from the Python project and subtract Math.round(new Date().getTime()) from it. The difference is almost always the same, but also unacceptable.

This is how I'm getting the UTC time from Python:

I solved this using ntpdate

I have installed this package apt install ntpdate and ran ntpdate -u pool.ntp.org. What this command does it to sync your system's clock. I did this on both of my systems and I had no issues with mismatch utc timestamp.

Of course I wonder if, when JS is ran on and android device, would that system be syncronized too? I'm assuming yes for now :)
