Robust
: It is highly robust. It even has community support and contribution and is easily usable.
Full Load
: Sqoop can load the whole table just by a single Sqoop command. It also allows us to load all the tables of the database by using a single Sqoop command.
Incremental Load
: It supports incremental load functionality. Using Sqoop, we can load parts of the table whenever it is updated.
Parallel import/export
: It uses the YARN framework for importing and exporting the data. That provides fault tolerance on the top of parallelism.
Import results of SQL query
: It allows us to import the output from the SQL query into the Hadoop Distributed File System.
