    As per my understanding, all the files where unstructured data are stored in HDFS system across the hadoop cluster. Now when we have to analyse those data we use Hive. Now my question is when we extract the data from a specific file, we provide the file name and load the data into Hive tables. So hive table supports so much volume of data and which database hive is having.

    Hi Prashant,

    Can you clarify your question more? Hive is the ‘database’ whose storage is HDFS, in simplified analogy. file can be loaded from local filesystem into HDFS and be the underlying data for hive table.

    Thanks,
    Yi
