Overview Sqoop is a top-level Apache project used to transmit data in hadoop and relational databases. Through sqoop, we can easily import data from a relational database to HDFS, or export data from HDFS to a relational database.Sqoop architecture: the sqoop architecture is very simple. It integrates hive, hbase, and oozie to transmit data through map-reduce tas

Today using Sqoop to import a table, I went to the database of data volume of 650 data, but I import data into the Hive table when there are 563 data, it is very strange, I think the data is wrong, and then more than a few times to import data discovery is the same problem.Then I went to the value of the data field ID and found out how the data that built the primary key could be empty. Then I went to look at the data in the database found that the da
