Andrew Purtell commented on HBASE-62:
-------------------------------------
I'd like to see these changes go in for 0.2, if possible. Changes are contained
largely to HTableDescriptor and HColumnDescriptor. The most signification
change elsewhere is support in HRegion for read only tables.
Patch attached. On second thought using a MapWritable was kind of ugly, so I
just used a map with byte[] keys and values and the utilities for
reading/writing byte arrays in Byte instead. Basically the same thing but the
code is cleaner.
The patch passes all 'ant test' tests for me.
These items are outstanding:
* Unit test for read-only tables -- New test TestReadOnly
* Unit test for user table and column metadata -- Probably can modify
TestHTable for this
* Migration script to deal with HTableDescriptor changes
I'll work on the unit tests.
