since we need migrate data-center, so our CDH also should be migrated to new env, the two data-center network is connectted.
there are near 1000+ tables in Hbase and HIVE, and also there are 100+ oozie jobs. we have just one day+ to migrate all data to new env.
total data size is not big, just 2TB.
my sloution is using hbase cluster replication to replicate all hbase tables, but it seems so difficult, there near 1000+ tables, it means i need add
about hive tables, it seems just has one solution, export all table and import to new env.
oozie jobs as i think just export source database to new database is ok, but since all the ip address has been changed, this is also a difficult point.
here i am asking peoples who has this experience of migration CDH to new env can give me some advises?
the hostname and ip address are diffierent from the old cluster, i have checked some file in /hbase, there are some files include namenode hostname, and you know hbase region has arranged by hbase master, all the thing is diffierent.
so i don't think cp /hbase to new cluster can migrate hbase.
