Subject Re: [DISCUSS] Spark-Kernel Incubator Proposal
Date Tue, 01 Dec 2015 07:33:19 GMT
Hi David & All,
The 'spark-kernel/torii' is a "good to have" tool.
Pardon me, I am not the judge in any way.After going through this thread and the referred
links, it seems, by giving it a decent publicity in Apache Spark (may be provide link, etc.),would
be sufficient enough for its survival and evolution, instead going through the entire 'apache
incubation'.
I am not undermining the incubation any way.  But for the prep work needed (license/trademark,
project rename, package rename) to make 'spark-kernel' incubation eligible and once in incubation,
it needs to keep up with the progress of Apache Zeppelin (which is incubating already).

Oh! that also makes me ask, can apache zeppelin & spark-kernel/torri be combined into
one ?!


Either way,  count me in for any help required with 'spark-kernel/torii'.
Thanking you.With RegardsSree

 Sorry for the late reply.
FYI there is an opensource project called torii already:
https://vestorly.github.io/torii/
Whether there is a trademark or not, I'd recommend a name that does not
collide with another project.
