Hi @qsdrqs,

I don't know how to help you with your question about Yarn, but if you want to find the systemd services available, you can do as follows:

[musikolo@MyPc ~]$ pacman -Ql hadoop | grep 'service$'
hadoop /usr/lib/systemd/system/hadoop-datanode.service
hadoop /usr/lib/systemd/system/hadoop-jobtracker.service
hadoop /usr/lib/systemd/system/hadoop-namenode.service
hadoop /usr/lib/systemd/system/hadoop-secondarynamenode.service
hadoop /usr/lib/systemd/system/hadoop-tasktracker.service

I hope it helps.

Hello! How can I start yarn service through this package, the script in hadoop/sbin may not recognize my config in /etc, and I can't find any systemd service on my computer to start it.

Looking forward to you reply!

When I installed this package by yay, I received the following message in the terminal.

yay -S --needed --noconfirm --noprogressbar hadoop

I did not modify the PKGBUILD. Does someone knows any solution?

How do I start this hadoop? I try:
sudo systemctl start hadoop-datanode hadoop-jobtracker hadoop-namenode hadoop-secondarynamenode hadoop-tasktracker
then check their status:
systemctl status hadoop-datanode hadoop-jobtracker hadoop-namenode hadoop-secondarynamenode hadoop-tasktracker
All of them failed. The jobtracker has this line:
Error: JAVA_HOME is not set and could not be found.
JAVA_HOME error:
Unable to start namenode and datanode: Hadoop ArchWiki to format a new distributed filesystem; for editing core-site.xml and hdfs-site.xml
jobtracker and tasktracker cannot start: running the commands in hadoop-jobtracker.service and hadoop-tasktracker.service under the hadoop account shows the reasons (12eason also mentioned that).

First thing, hdfs, mapred, container-executor, rcc and yarn all need to be linked to /usr/bin along with hadoop. Hdfs especially has a lot of the functions previously done by hadoop.

Secondly, the hadoop package provides shell scripts under sbin/ to start and stop instances and these would be less prone to breakage if used in the systemd scripts. As it is, many commands systemd uses are depreciated.

There's mirror problems for hadoop:

Can you symlink /usr/lib/hadoop/bin/mapred to /usr/bin/mapred

I'm looking to save time for others, not myself. The problem is that xz is very useful in the repos where traffic reduction is worth any cost. xz is counter productive on the AUR.

Hi, I found your discussion about the PKGEXT.
But have you ever tried to compress the package in parallel?(by setup 'xz -T0' in /etc/makepkg.conf)

I got
.pkg.tar.xz: 530% cpu 26.731s
with CPU E5-2660 0 @ 2.20GHz

And I think it may take much less time on a i3/5/7 cpu

`hadoop-jobtracker.service` make use of command `/usr/bin/hadoop jobtracker` but is deprecated. The ouput of that command suggest to use the new yarn command.
