Hi, We are using a new Datacenter and have to move the data from old cluster to new cluster. Cluster Old New HDFS 2.7.1.2.3 3.1.1.3.1 Hbase 1.1.2.2.3.2.0 2.0.0.3.1 Zookeeper 3.4.6.2.3 3.4.9.3.1 OS Debian 7 (Wheezy) Debian 9 (Stretch) Since the major versions are different, I only know of one option for data migration: CopyTable. (+ SyncTable) Are there any challenges to keep note of, since we have different OS. Is there a way to online replicate the data? We have around 40 tables and around 1TB of data for each. How many copy table operations can be run parallel? Thank you ... View more
