How to deploy ambari for an existing hadoop cluster -

-

as mention in title, can skip step of install hadoop cluster cluster exist , in service?

ambari relies on 'stack' definitions describe services hadoop cluster consists of. hortonworks defined custom ambari stack, called hdp.

you define own stack , use services , respective versions wanted. see ambari wiki more information defining stacks , services.

that being said, don't think it's possible use pre-existing installation of hadoop ambari. ambari used provision , manage hadoop clusters. keeps track of state of each of stacks services, , states of each services components. since cluster provisioned difficult (maybe impossible) add ambari instance.

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
