I have downloded cassendra and unzip and untared the folder.

in online installation notes it is written that

"set filesystem paths in conf/cassandra.yaml and conf/log4j-server.properties"

"Start Cassandra by invoking bin/cassandra -f on the command line in the directory where Cassandra was unpacked. Read output to check that Cassandra started successfully."

I tried to invike cassandra using "bash"(bash cassandra -f) command as instructed.
but it dosent say the cassandra is started successfully.

I am pretty new to linux
Please help
Thanks in advance.

You give us very little information which makes it difficult to offer any help. What distro are you using? For example if you're using Debian then you can follow the instructions found here. There may well be a package for your distro.
jdk

and WHAT exactly did you download?
http://cassandra.apache.org/
http://cassandra.apache.org/download/

did you fallow the instructions ?
http://wiki.apache.org/cassandra/GettingStarted
and in step 0
are the PRE-requisites installed AND WORKING

also according to the instructions
there ARE Debian packages
for a deb
http://wiki.apache.org/cassandra/DebianPackaging

for redhat
-- rpm's
http://rpm.datastax.com/community/noarch/
PREREQUSITS and source
--google
--this looks good

If you might be referring to an early release of Linux Mint Cassandra, it has not been supported for 6 years so hopefully that's not it.

sorry for giving u such a little information.

What i m trying to do is tieing Cassandra with Titan the grapg database.
I am not using any other software or any distro(in fact I dont know what a distro means. but I would like to know it)

I already installed Titan graph DB and want to make it distributed. so as per recomendation I am using Cassandra.

I have downloded latest cassandra(2.1.2). titan graphdb is 5.something
my machine has 4 gb ram.

first I will try on my machine and then I will go for cluster implementation.

Here are somee last line when I am trying to run cassandra

"Distro" means the "variety of linux". Common distros are Debian, RHEL, CentOS, Slackware, Fedora, Ubuntu, Linux Mint, and so on. Which one are you using? Where did you get the Cassandra that you installed? Was it from Apache? Please answer these questions if you expect any kind of help.
jdk

I am using fedora 20. And I got Cassandra from apache.

Thanks. That's what I needed. Here you go. Try this. That should sort you out nicely. Let us know how you make out.
jdk

Are you planning on using Cassandra on Fedora in production? That is not good.

Sir, This is for project purpose.

I will do this steps and get back to u JDK.
Thanks and regards,
Akash Patel
