Hive Partition Subdirectory. Partitioning in hive is conceptually very simple: In hadoop hive, data is stored as files on hdfs, whenever you partition the table in hive, it creates sub directories within main. I want to add all data of. Hive is a data warehouse infrastructure built on top of hadoop that provides data summarization, querying, and analysis. I have data organized in directories in a particular format (shown below) and want to add these to hive table. In hive, tables are created as a directory on hdfs. Here is an example where there are 3 days. One logical table (partition) for each distinct value. Hive partition is a way to organize large tables into smaller logical tables based on values of columns; You create the table, then add each partition manually via an alter table command. Hive doesn't know about those directories until you tell it about them, so there's no way to access the partitions without adding. We define one or more columns to partition the data on, and then for each unique combination of values in those columns, hive.
