I have a very small cluster of 4 nodes :
– 1 master on which were also installed a data node
– 3 slaves (on which there is data node)
After a short training around Big Data technology, I realized it was better to remove the data node from the master, in order to release some resources on the master.
So, I went into the ambari user interface dashboard, and then in the master node, in the services installed on this master node, and, for the data node, I performed a “decomission”.
And now this data node is just blinking in orange.
So I contact you because I’m not sure about what to do now.
1. How can I request a new distribution of the data, now this data node is decomissioned
2. Will this data node completely disappear from ambari ? Do I have to do something more ?
