I thought this is easy, but couldn't find any answer. Hopefully, this can be done using command line tools. Or a Python tool.
Or at least find out how many hfiles?

The command hbase hbck -details <tablename> can be used to get the table details and will contain the region information required. The output of the above-mentioned command can be parsed to obtain the region-info for the required table.
In HBase Architecture, a region consists of all the rows between the start key and the end key which are assigned to that Region. And, those Regions which we assign to the nodes in the HBase Cluster, is what we call “Region Servers”. Basically, for the purpose of reads and writes these servers serves the data.
Hey, list is the command that is used to list all the tables in HBase. Given below is the syntax of the list command.
You've got a few options:
1 Via HTTP: http://[your_hbase_master]:60010/table.jsp?name=[your_table]
2 Command-line:
$ hadoop fs -ls /hbase/[your_table]

You'll get one directory per region (excluding .tmp y .tableinfo):
3 In JAVA you can use HBaseAdmin.getTableRegions(byte[])
