When truncate HBase Table Splits get removed

Question

I created a Table namely DEMO_TABLE and inserted some data, but I wanted to clear out that table for that,

truncate "DEMO_TABLE"

But this removes all pre-splits given to that Table. Can Anybody explain this behavior?

Answer 1

If you are using HBase 0.98 or greater version, you can use truncate_preserve command in HBase shell. This will retain the previous region boundaries defined by the pre-split.
