Start the Ambari Server
Run the following command on the Ambari Server host:
ambari-server start
To check the Ambari Server processes:
ambari-server status
To stop the Ambari Server:
ambari-server stop
Note | |
---|---|
If you plan to use an existing database instance for Hive or for Oozie, you must prepare to use an existing database before installing your Hadoop cluster. |
On Ambari Server start, Ambari runs a database consistency check looking for issues. If
any issues are found, Ambari Server start will abort and
display the following message: DB configs consistency check
failed
. Ambari writes more details about database consistency check results
to the/var/log/ambari-server/ambari-server-check-database.log
file.
You can force Ambari Server to start by skipping this check with the following option:
ambari-server start --skip-database-check
If you have database issues, by choosing to skip this check, do not
make any changes to your cluster topology or perform a cluster upgrade until you correct the
database consistency issues. Please contact Hortonworks Support and provide the
ambari-server-check-database.log
output for assistance.
