Have you had the same issue on 2.1.3?

>                 Key: CASSANDRA-8404
>                 URL:
>             Project: Cassandra
>          Issue Type: Bug
>         Environment: I am using Cassandra 2.1.1 on 32 bit Ubuntu 12.04. I am running
the program with -Xmx1000M
> manish@manish[~]:> uname -a
> Linux manish 3.2.0-72-generic-pae #107-Ubuntu SMP Thu Nov 6 14:44:10 UTC 2014 i686 i686
i386 GNU/Linux
>            Reporter: Manish
>             Fix For: 2.1.4
>         Attachments:, cassandra.yaml
> I am able to create SSTable for one file of 10M rows but not for other file. The data
file which works is subscribers1.gz and data file which does not work is subscriber2.gz. Both
files have same values in first column but different values for second column. I wonder why
CQLSSTableLoader does not work for different set of data. 
> Program expected unzipped txt files. So please unzip files before running program. What
I have observed is High GC when program processes around 5.2M lines of file subscriber2.gz.
It is able to process till 5.8M lines with very frequent Full GC runs. It is not able to process
beyond 5.8M rows because of memory not being available.
> I have attached and cassandra.yaml I used for creating sstable. In classpath
I am specifying all jars of lib folder of extracted apache-cassandra-2.1.1-bin.tar.gz 
> Jira does not allow a file of size greater than 10 MB. So I am sharing data files in
google drive.
> link to download subscribers1.gz
> link to download subscribers2.gz
