background
For information about how to do data migration stop HBase cluster service has always been more of a question asked of cloud HBase, there are many open source tools or HBase itself integrated solution in terms of performance, stability, experience is not very good Therefore BDS Ali cloud provides migration services to help customers implement cloud TB-level data on the scale of non-stop migration

An Introduction
Open source programs
HBase non-stop migration mainly includes three parts: migration, real-time data table structure synchronization, the total amount of historical data migration
Table Structure Migration
For table structure migration, the open source DataX or HBase table structure itself does not provide a migration function can only be manually build the table, the manual construction of the table there will be a few questions:
- If the source table data clusters are more customers to manually build the table too much trouble
- After the construction of the table may have overlooked the manual partition table, leading to the target partition table is very reasonable, complete migration
