> In case of replication to cloud both dump and load are executed in the source cluster. This push based replication is done to avoid computation at target cloud cluster. In case in the source cluster, strict managed table is not set to true the tables will be non acid. So during replication to a cluster with strict managed table, migration logic same as upgrade tool has to be applied on the replicated data. This migration logic is implemented only in hive4.0. So it's required that a hive 4.0 instance started at the source cluster. If the source cluster has hadoop-2 installation, hive4 has to be built with hadoop-2 and necessary changes are required in the pom files and the shim files.
> 1. Change the pom.xml files to accept a profile for hadoop-2. If hadoop-2 profile is set, the hadoop version should be set accordingly to hadoop-2.
> 2. In shim creare a new file for hadoop-2. Based on the profile the respective file will be included in the build.
> 3. Changed artifactId hadoop-hdfs-client to hadoop-client as in hadoop-2 the jars are stored under hadoop-client folder.
