Is ambari agent(v1.6.0) able to install component in parallel?
Hi ambari users,
I am trying to deploy hadoop cluster by ambari, and I want it to as fast
as possible.
When I digged into ambari agent source code, I found a parameter in
ActionQueue.py named "MAX_CONCURRENT_ACTIONS = 5", but I did not find any
place invoke it.
So I wonder is amabri agent able to install component in parallel?
If not, is there any other method to accelerate the whole installation
process?
Thanks in advance for any suggestions.
---------------------------------
Best Regards

Hi,
Also you may try using yum-axelget to get packages downloaded in multiple
threads. So packages are downloaded faster.
Regarding concurrent task execution at agent, this experimental feature
has been implemented at some time, but it caused additional troubles (e.g.
concurrent yum invocations, task timeouts due to longer task execution and
so on), so it has been removed.

Hello,
you can also setup local repositories to speed up installation:
http://docs.hortonworks.com/HDPDocuments/Ambari-1.6.0.0/bk_using_Ambari_book/content/ambari-chap1-6.html
Usually this helps a lot in cases when nodes share single internet
connection.

Hi,
Ambari agent uses default package manager to install packages for
components (yum for RedHat, CentOS and zypper for SLES). yum or zypper
can't be run in parallel in a single node, they create locks once they
started. But you will have hadoop components installing in parallel on
different nodes.
