Hi !
We have an existing hadoop cluster, which consists of vanilla apache hadoop
2.7.3(not hdp) and apache hive 1.2.1(not hdp). It has been running for about 2
years in production. It has lots of important data.
We want to use Ambari. Since the version of hadoop in hdp 2.6.3 is hadoop
2.7.3 and the version of hive is hive 1.2.1, we think we might manage the
cluster with Ambari. Here is what we plan to do:
1. Install ambari 2.6.0.0
2. Install hadoop、hive(hdp2.6.3) with Ambari
3. Replace the data(include metadata and block data) of hdp HDFS with our
existing HDFS data
4. Replace the metadata of hdp hive with our existed hive metadata
5. Use Ambari to manage the whole cluster
Does this approach make sense? Does anyone have tried this before? What are
the risks?
Thanks in advance!
