Thanks,Sergey. These days, I want to move a table from one hbase cluster to another hbase cluster, and there are the same table's schema. So I want to move a region's storefile to another table's region corresponding directory, and the key bound of regions are overlapped. For example: Cluster | Table | Region's key bound cluster1 | dat | [1ffff,2ffff] cluster2 | dat | [2bfff,31fff]
In my opinion , if region files in cluster2 are move into cluster1's regions, and make compaction（Minor && Major） upon the first region, it will prune the improper key in (2ffff,31fff]. However I found hbase compaction cannot support that. Any idea would be thankful. 2013/7/11 Sergey Shelukhin <ser...@hortonworks.com> > You should not have to manually take care of region bounds in normal > circumstances (unless you are reading the file from coprocessor in some > special way, or something like that).
