Hi Gaurav, Region information of Table is stored in meta table. If you want to delete a region, actually you should delete a row in meta table. In HBase shell:
deleteall 'hbase:meta', 'ROW_FROM_META_WITH_YOUR_TABLE' If you are not sure what the row you want to delete run a scan on the META or dump its value into a file: echo "scan 'hbase:meta' "| hbase shell &> dump.txt then find your row and delete it. As you asked after region delete operation table has some holes. make sure you run hbase hbck -repair to fix those.
