public class HTableDescriptor
extends Object
implements TableDescriptor, Comparable<HTableDescriptor>

HTableDescriptor contains the details about an HBase table such as the descriptors of all the column families, is the table a catalog table, hbase:meta , if the table is read only, the maximum size of the memstore, when the region split should occur, coprocessors associated with it etc...
