kandi X-RAY | ambari-metrics Summary
Ambari Metrics System ("AMS") is a system for collecting, aggregating, serving and visualizing daemon and system metrics in Ambari-managed clusters. The original JIRA Epic for Ambari Metrics System can be found here: First official release of AMS was with Ambari 2.0.0. With metrics repro split, the aim is to be able to release the sub-project with separate cadence than Ambari. The Metrics Collector is daemon that receives data from registered publishers (the Monitors and Sinks). The Collector itself is build using Hadoop technologies such as HBase Phoenix and ATS. The Collector can store data on the local filesystem (referred to as "embedded mode") or use an external HDFS (referred to as "distributed mode"). It is a fully distributed collection and aggregation system starting from 2.7.0. Please refer to the wiki for more detailed info:

QUESTION
I am currently setting an Ambari cluster and getting stuck at the ambari-web build stage
ANSWER
Answered 2021-Mar-06 at 05:02I'm sure you won't be able to do that. Because ambari will need to download the repo from hortonwork. Eventually it will still fail, since there is no public for the hortonwork from 31/01/2021.
QUESTION
I am following the guide :
https://cwiki.apache.org/confluence/display/AMBARI/Installation+Guide+for+Ambari+2.7.5
and with this info Ambari 2.7.5 installation failure on CentOS 7 , I managed to overcome the ambari-admin error, but now I am facing a new one :
...ANSWER
Answered 2020-Jul-25 at 07:43As you can see in the error, the dependency chain includes at least
org.apache.phoenix:phoenix-core:jar:5.0.0.3.1.4.0-315
, which is accessible at
https://repo.hortonworks.com/content/groups/public/org/apache/phoenix/phoenix-core/
And there is no version 3.1.4.0-315
listed there, which will cause the build to fail without some other location where such packages exist, which I am not aware of any outside of the new Cloudera repo listed in the comments.

I followed the instructions on this post:
Ambari 2.7.5 installation failure on CentOS 7
Unfortunately, I am still getting an error:
...ANSWER
Answered 2020-Jun-12 at 00:16@Dribble. While working on Ambari 2.7.5 for SUSE 12, I ran into the same error. You need to make sure to get maven version right first (Apache Maven 3.3.9 or later).
The specific package dependency errors are fixed by editing ambari-web/pom.xml and setting the node version to version installed in building operating system.
Once I did this, the build completed the Ambari Web Steps. You may run into similar dependency failures with other packages. You can see the following recent posts for more details including specific versions:
Error building ambari 2.7.5 Centos 7 (fails at ambari-admin step)
QUESTION
I am trying to build ambari 2.7.5 on Centos 7 per these instructions, which is relatively straightforward.
However, when the build gets to ambari-admin, it fails. There are several posts out there that describe a supposed solution to this- which is editing "...ambari-admin/pom.xml" and setting the node and npm versions to match the versions installed on the server.
Sadly, this does not work for me. And I have tried the versions of node/npm that come with Centos(EPEL), I have tried the LATEST node/npm versions from apache, and I've tried older versions. I edit the pom.xml file to match.
In the end, it is always the exact same failure regardless of the dozens of attempts using the above.

Answered 2020-Jun-08 at 19:52@RohitSharma You should be able to build the correct Ambari Metric RPMS during your ambari 2.7.5 build.
