I used to install hadoop apache and use user defined file path.

Now I want to use ambari and hdp version,but I have a lot of data ,about tens of TB data.

Is there a way to use ambari manage the exists hadoop cluster?

And then I want to upgrade to ambari and hdp version,is there a way not stop the exists cluster for a too long time?

@darkz yu - this is an Ambari takeover situation. However, there are some manual steps involved and there are some tricky situations, so we recommend a professional service engagement to help make this successful. That will include both having Ambari take over the existing cluster as well as perform the upgrade.
