Hi, I am new to Hive, I am reading the doc which is available on Apache site and try to create a correlation between hadoop and Hive. so please help me to understand this: As per my understanding, all the files where unstructured data are stored in HDFS system across the hadoop cluster. Now when we have to analyze those data we use Hive. Now I have some question which I am not able to get :
1.When engineer/buisnessuser want to analyze the data, which is available on any of the file on HDFS cluster, so what is the steps to get the desired file and analyze the file using hive. 2.Is Hive stores all the data in their tables after the analysis permanently? 3.Is Hive itself a database?
