Life cycle management of ats-hbase
Depending on requirements, the yarn-ats
user can perform the
following life cycle management operations on the ats-hbase
service: start,
stop, or destroy the service; and scale up or scale down HBase component instances for the
service.
The yarn-ats
user can perform the life cycle management operations
by using either REST APIs or the command line interface.
Stopping the ats-hbase service
REST API:
Consider the following examples of using the PUT method for stopping the service:
Secure cluster:
Ensure that you run kinit
with
/etc/security/keytabs/yarn-ats.hbase-client.headless.keytab
.
curl -k --negotiate -u: -H "Content-Type: application/json" -X PUT http://<ResourceManagerHost>:<ResourceManagerPort>/app/v1/services/ats-hbase -d '{
"state": "STOPPED"
}'
Non-secure cluster:
curl -k -u: -H "Content-Type: application/json" -X PUT http://<ResourceManagerHost>:<ResourceManagerPort>/app/v1/services/ats-hbase?user.name=yarn-ats -d '{
"state": "STOPPED"
}'
Command
yarn app -stop
command to stop the
service.yarn app -stop ats-hbase
Starting the ats-hbase service
REST API:
Consider the following examples of using the PUT method for starting the stopped service:
Secure cluster:
Ensure that you run kinit
with
/etc/security/keytabs/yarn-ats.hbase-client.headless.keytab
.
curl -k --negotiate -u: -H "Content-Type: application/json" -X PUT http://<ResourceManagerHost>:<ResourceManagerPort>/app/v1/services/ats-hbase -d '{
"state": "STARTED"
}'
Non-secure cluster:
curl -k -u: -H "Content-Type: application/json" -X PUT http://<ResourceManagerHost>:<ResourceManagerPort>/app/v1/services/ats-hbase?user.name=yarn-ats -d '{
"state": "STARTED"
}'
Command
yarn app -start
command to start the stopped
service.yarn app -start ats-hbase
Scaling up or scaling down HBase component instances for the ats-hbase service
ats-hbase
.Note | |
---|---|
The number of the HBase
master component instances cannot be increased by more than two at a
time. |
REST API:
In the following examples, the number of region server instances is scaled to a value of 10:
Secure cluster:
Ensure that you run kinit
with
/etc/security/keytabs/yarn-ats.hbase-client.headless.keytab
.
curl -k --negotiate -u: -H "Content-Type: application/json" -X PUT http://<ResourceManagerHost>:<ResourceManagerPort>/app/v1/services/ats-hbase/components/<component> -d '{
"number_of_containers": "10"
}'
curl -k -u: -H "Content-Type: application/json" -X PUT http://<ResourceManagerHost>:<ResourceManagerPort>/app/v1/services/ats-hbase/components/<component>?user.name=yarn-ats -d '{
"number_of_containers": "10"
}'
Command
yarn app -flex
command and specify the number of component
instances to scale.
yarn app -flex ats-hbase regionserver 10
Destroying the ats-hbase service
REST API:
Consider the following examples of using the PUT method for destroying the service:
Secure cluster:
Ensure that you run kinit
with
/etc/security/keytabs/yarn-ats.hbase-client.headless.keytab
.
curl -k --negotiate -u: -H "Content-Type: application/json" -X DELETE http://
<ResourceManagerHost>:<ResourceManagerPort>/app/v1/services/ats-hbase
curl -k -u: -H "Content-Type: application/json" -X DELETE http://
<ResourceManagerHost>:<ResourceManagerPort>/app/v1/services/ats-hbase?
user.name=yarn-ats
Command
yarn app -destroy
command to destroy the
service.yarn app -destroy ats-hbase
