Sqoop is
a tool which can transfer bulk data from a relational database to Hadoop and
vise-versa. For better performance and optimal system utilization it does
parallel data transfer and load balancing among the nodes. It can read/write data
from/to Oracle, Teradata, Netezza, MySQL, Postgres, and HSQLDB. While importing
the data to hdfs it can save the data in different format e.g. ORC, Avro,
Parquet etc.
