Hi Team,

we see logs of various hadoop services are stored in /var/log

can we change it to our customized location

if i dont want to store logs in below location then

/var/log/ambari-agent/ /var/log/ambari-metrics-monitor/ /var/log/ambari-server/ /var/log/hbase /var/log/zookeeper

i see in ambari changing log location is disabled ?

This is easier done at install time. After installation, your best bet is to create symbolic links. Please see the following thread.

You need to stop Ambari services to allow changes to configurations like log location. During that time, your cluster could still run, but you will have a gap in Ambari logs and metrics.

For service logs , log directory is controlled by a configuration property. You can modify the configuration property .

Look at https://cwiki.apache.org/confluence/display/AMBARI/Modify+configurations for more details.

You will have to restart the service for the changes to take effect.

I want to be sure I understand your post. Are you saying that modifying a single Ambari property will relocate logs for all components on a restart? If so, can share what the name of that property is? The page you linked to does not have a single mention of log location.

In a perfect world, I would have left plenty of room under /var for logging, but we have a heavily used cluster with a lot of data and constant crashes from full /var on many of the machines. I need to move everything to a new location.
