示例1: verifyTags

/**
* This verifies that each cell has a tag that is equal to its rowkey name. For this to work
* the hbase instance must have HConstants.RPC_CODEC_CONF_KEY set to
* KeyValueCodecWithTags.class.getCanonicalName());
* @param table table containing tagged cells
* @throws IOException if problems reading table
*/
