with the right ftp client JAR on your classpath (I forget which), you can use 
ftp:// a a source for a hadoop FS operation. you may even be able to use it as 
an input for some spark (non streaming job directly.

Thanks Marcelo. But our problem is little complicated.

We have 10+ ftp sites that we will be transferring data from. The ftp server 
info, filename, credentials are all coming via Kafka message. So, I want to 
read those kafka message and dynamically connect to the ftp site and download 
those fat files and store it in HDFS.

And hence, I was planning to use Spark Streaming with Kafka or Flume with 
Kafka. But flume runs on a JVM and may not be the best option as the huge file 
will create memory issues. Please suggest someway to run it inside the cluster.

Why do you need to use Spark or Flume for this?

You can just use curl and hdfs:

  curl ftp://blah<ftp://blah/> | hdfs dfs -put - /blah

What is the best way to bring such a huge file from a FTP server into Hadoop to 
persist in HDFS? Since a single jvm process might run out of memory, I was 
wondering if I can use Spark or Flume to do this. Any help on this matter is 
appreciated.

I prefer a application/process running inside Hadoop which is doing this 
transfer

Thanks.
