Example: > {code} > public static final HTableDescriptor ROOT_TABLEDESC = new HTableDescriptor( > HConstants.ROOT_TABLE_NAME, > new HColumnDescriptor[] { new HColumnDescriptor(HConstants.CATALOG_FAMILY, > 10, // Ten is arbitrary number. Keep versions to help debuggging. > Compression.Algorithm.NONE.getName(), false, true, 8 * 1024, > HConstants.FOREVER, false) }); > {code} > We can remove it from 0.21 since we force sync everything catalog. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
