Andrew Hutchings	874596c6cd	MCOL-309 Implement Information Schema tables ... This patch does the following: * Fix a year storage issue in the datestamp for the columnstore tables metadata table (note that any previous tables will still have the incorrect year stored). * Expose the table creation date in CalpontSystemCatalog::getTables() * Add an INFORMATION_SCHEMA table listing the tables in ColumnStore (similar to systable) * Add an INFORMATION_SCHEMA table listing the columns in ColumnStore (similar to syscolumn) * Add an INFORMATION_SCHEMA table listing the extents in ColumnStore (similar to the editem tool but with additional file information) * Modifies the build system and scripts to support the new tables	2016-11-14 15:44:20 +00:00
