-----------------------------------------------
[~jasobrown] [~snazy] - Just wanted to know , if i create a branch locally
under my own account on github , how will it be made public , as in how will it
appear to all in - https://github.com/apache/cassandra/ . I was of the opinion
that a separate branch would be created here -
https://github.com/apache/cassandra/branches ( say for eg : ppc64le/trunk ) and
all the changes pertaining to ppc64le would be up-streamed here.
Let me know your views about this and how will the changes made for ppc64le -
development branch be made public via apache cassandra repository .
> Increasing the per thread stack size to atleast 512k

> 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

> Thereafter i was able to start the Cassandra server successfully.
> Could you please consider increasing the stack size to '512k' in

> 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
