Description

HTableDescriptor is deprecated as of release 2.0.0, and will be removed in 3.0.0. This patch replaces all usages of HTableDescriptor and HColumnDescriptor in the hbase-shell module so that HTableDescriptor can be removed.

There a few other consequences of this change:

• Ruby methods relating to HTableDescriptor and HColumnDescriptor have been removed. This is noted in "Release Note" on this issue.
• We no longer import constants from HTableDescriptor and HColumnDescriptor into the ruby HBaseConstants module. Instead, we import them from ColumnFamilyDescriptorBuilder and TableDescriptorBuilder.
