Microsoft has released a new tool/connector based on SQOOP for those looking out to transfer data between SQL Server 2008 R2 and Apache Hadoop. Since it is based on Sqoop, it also supports different databases incuding Oracle and MySQL. The tool is currently available as CTP and is free of charge (atleast for the time-being)
Sqoop is an open source connectivity framework that facilitates transfer between multiple Relational Database Management Systems (RDBMS) and HDFS. Sqoop uses MapReduce programs to import and export data; the imports and exports are performed in parallel with fault tolerance.
Microsoft announced “The Microsoft SQL Server Connector for Apache Hadoop extends JDBC-based Sqoop connectivity to facilitate data transfer between SQL Server and Hadoop, and also supports all the features as mentioned in SQOOP User Guide on the Cloudera website. In addition to this, this connector provides support for nchar and nvarchar data types.”
