Hive Partition Overwrite. Hive insert overwrite partition is a hiveql command that allows you to insert data into a partition of a table, overwriting any existing data. Hive partitions are used to split the larger table into several smaller parts based on one or multiple columns (partition key, for example, date, state e.t.c). Able to see them via. In this post, we’ll go through how to replace existing partitioned data in hdfs subdirectories that have already been created. To use it, you need to set the spark.sql.sources.partitionoverwritemode setting to dynamic, the dataset needs to be partitioned, and. I tried the above scenario but see different results. First did insert overwrite which created a,b,c,d,e partitions. The hive partition is similar to table partitioning available in sql server or any other rdbms database tables. In summary, load data hiveql command is used to load the file into a hive existing or new partition of the table, use insert into to insert specific rows into a partition, and finally, use insert overwrite to overwrite the partition with the new rows. Insert overwrite table tablename1 [partition (partcol1=val1, partcol2=val2.) [if not exists]].
