Dear ch, HBase tables are stored in HDFS following a hierarchy that mimics your table's schema. In particular, check out the following section of the ref guide: http://hbase.apache.org/book/trouble.namenode.html#trouble.namenode.hbase.objects . Once you understand that, you can basically just do a recursive list through HDFS at the granularity level you'd like to count the number of HFiles.
