Thanks for your understanding, [~amitkumar_ghatwal]!
The approach to do all the development in a fork on github is right.

We'd appreciate to see it working on ppc64le. Looking forward to see progress on this!
Resolving this ticket as "incomplete" for now, but feel free to open another ticket. #cassandra-dev IRC channel is the right place for questions on development and infra questions.

> Hi All,
> I followed the below steps 
> ```
> $ git clone https://github.com/apache/cassandra.git
> $ cd cassandra/
> $ ant
> $ bin/cassandra -f
> The stack size specified is too small, Specify at least 328k
> Error: Could not create the Java Virtual Machine.
> Error: A fatal exception has occurred. Program will exit.
> ```
> After getting this , i had to upgrade the thread stack size to 512kb in 'conf/jvm.options'
> ```
> $ git diff conf/jvm.options
> diff --git a/conf/jvm.options b/conf/jvm.options
> index 49b2196..00c03ce 100644
> --- a/conf/jvm.options

> +-Xss512k
>  # Larger interned string table, for gossip's benefit (CASSANDRA-6410)
>  -XX:StringTableSize=1000003

> Thereafter i was able to start the Cassandra server successfully.
> Could you please consider increasing the stack size to '512k' in 'conf/jvm.options.
> Similar to  "https://issues.apache.org/jira/browse/CASSANDRA-13300". Let me know if we can increase the stack size in the Apache Cassandra trunk.
> Thanks for support provided so far , and let me know
