As the name suggests, veracity is related to the accuracy and trustworthiness of the data. Data veracity refers to the various issues with data such as biasedness, the reliability of data sources, noise in the data, accuracy of data, etc. It is one of the most essential characteristics of the Hadoop system. It also involves processing, analysing, and interpreting the data in the desired way to yield meaningful results. However, it may sometimes get difficult to track the data source and quality when multiple datasets are combined. Hence, veracity is one area which still needs improvement.
