configs.sh not supported from 2.6.4 HDP version

[#1]

hi all,

Until HDP version - 2.6.4 we can use the configs.sh as the following example

( in this example we print all variables that relevant to the config type - yarn-site )

cluster name - HDP

config type - yarn-site

ambari server - localhost

 /var/lib/ambari-server/resources/scripts/configs.sh get localhost HDP yarn-site
########## Performing 'GET' on (Site:yarn-site, Tag:version1512057597218)
"properties" : {
"hadoop.registry.rm.enabled" : "true",
.
.
.

from 2.6.4 version ( and include config.sh isn't supported )

/var/lib/ambari-server/resources/scripts/configs.py get localhost HDP yarn-site
Usage: configs.py [options]
configs.py: error: One of required options is not passed

so we using now the configs.py instead

but seems that flags in configs.sh not as in configs.py

what is the right syntax to use the configs.py in order to get all variable according to the config type as we do on configs.sh ?

 /var/lib/ambari-server/resources/scripts/configs.py get localhost HDP yarn-site
Usage: configs.py [options]
configs.py: error: One of required options is not passed

Here is a simple example of config.py:

# /var/lib/ambari-server/resources/scripts/configs.py --user=admin --password=admin --port=8080 --action=get --host=localhost --cluster=Sandbox --config-type=yarn-site

Here is another example in which we are setting a property in cluster-env. Notice "-k" means Key and "-v" for value. Following command will set the Auto Start for Cluster services to true.

# /var/lib/ambari-server/resources/scripts/configs.py --user=admin --password=admin --port=8080 --action=set --host=localhost --cluster=Sandbox --config-type=cluster-env -k "recovery_enabled" -v "true"

@jay thank you , another little equation regrading that

in configs.sh in order to set new value we do that ( for example )

/var/lib/ambari-server/resources/scripts/configs.sh set localhost HDP yarn.timeline-service.recovery.enabled true

what is the syntax for configs.py?

@Michael Bronson

Yes we can set individual properties as well like following:

# /var/lib/ambari-server/resources/scripts/configs.py --user=admin --password=admin --port=8080 --action=set --host=localhost --cluster=Sandbox --config-type=yarn-site -k "yarn.timeline-service.recovery.enabled" -v "true"

Hi ,

I am trying to use this in my environment but fails. Its a kerberized environment and SSL enabled. "XXX" is where I replace the right values.

@Mayank Bhatt do add "--protocol https --port 8443" options if ambari is running on HTTPS.
