How and What will I have to test once the data is moved from RDBMS to HDFS?

Check the number of records in RDBMS and number of records written to HDFS. you can check the records in RDBMS using sqoop query and check this with HDFS records. There are chances that the number of records in HDFS are more than that of RDBMS due to linefeed character in the RDBMS fields.

Is there any example of Spark deployment without Hadoop in production?

Hi Soujaya... Though spark can run without HDFS/Hadoop the real power of hadoop lies in parallel processing and distributed storage. This is not available in other frameworks. So you hardly get spark without hadoop in production.

How do I install Hadoop on Windows 8.1?

Hadoop is installed on Linux base systems and not on windows. For windows you can use virtual machine provided by cloudera. This will be a standalone machine for practice purpose only.
