[#1]

When we installed any components vi amabri then it run yum install command in the background and if components is big in size then it takes time.

2017-02-06 05:23:04,413 - Installing package ambari-metrics-hadoop-sink ('/usr/bin/yum -d 0 -e 0 -y install ambari-metrics-hadoop-sink')

"/var/log/yum.log" file can be checked to know if a package is installed properly or not. Although it won't show the percentage.

Example:

# cat /var/log/yum.log | grep ambari-metrics-monitor
Feb 06 10:38:35 Erased: ambari-metrics-monitor
Feb 06 10:39:36 Installed: ambari-metrics-monitor-2.4.2.0-136.x86_64

.

For little more DEBUG informations you might want to increase the "debuglevel" in the file "/etc/yum.conf".

debuglevel=value

Where value is an integer between 1 and 10. Setting a higher debuglevel value causes yum to display more detailed debugging output. debuglevel=0 disables debugging output, while debuglevel=2 is the default.

I tried to tail the log but it was not updating.

You can check /var/log/messages to see if installation has started.

Also if you want to check how much data has been downloaded, yum keeps package in yum cache while downloading, you can run 'du -sh' in watch command to check the status.

Example.

Before downloading package

[root@prodnode1 ~]# ls -lrt /var/cache/yum//x86_64/6/Updates-ambari-2.4.0.1/packages/
total 0

Download started

[root@prodnode1 ~]# /usr/bin/yum -d 0 -e 0 -y install ambari-metrics-hadoop-sink

Status of cache directory

[root@prodnode1 ~]# ls -lrt /var/cache/yum//x86_64/6/Updates-ambari-2.4.0.1/packages/
total 4552
-rw-r--r--. 1 root root 4660232 Aug 30 20:49 ambari-metrics-hadoop-sink-2.4.0.1-1.x86_64.rpm

After installation is complete, package gets removed from cached location.

You can run something like below to keep watch over download

[root@prodnode1 ~]# watch du -sh /var/cache/yum//x86_64/6/Updates-ambari-2.4.0.1/packages/ambari-metrics-hadoop-sink-2.4.0.1-1.x86_64.rpm
