Hazelcast enable rest-api - api

I have hazelcast version 3.8.3. I want to enable rest api.
I wrote in the config:

The rest-api section was added in 3.12, you're using 3.8.
An upgrade should sort it.
The latest Hazelcast 3 series is 3.12.9, but it's still old.
Current Hazelcast is Hazelcast 5. If you can upgrade, going to 5.1.1 would be better, the very latest (as of time of writing) -- even faster, more features, etc.

Which version to use as a base for integration?

I see there are list active version of karate available.
Our team develop tool for reporting (reportportal.io) and our users are asking for support of various versions.
As far as i see, there is no back compatibility between 0.9.2 - 0.9.3 - 0.9.4 - 0.9.5RC5
support and track integrations for each of minor versions is overhead.
Could you please updated on any roadmap, ETA and strategy for version compatibility, so we can focus on 1 certain version.
thank you in advance.
Use 0.9.5.RC5 and the develop branch in GitHub. The plan is to release 0.9.5 final within a month.

Apache Lucene Version

I am just starting a student project for a lesson based on apache lucene and the data that i am going to process with this tool is critics about restaurants from yelp.
What version do you recommend as the most stable for this purpose?
I think that if you are starting from scratch there's no reason to use an old version. Use the latest version (8.0). Lucene releases are always very stable in my experience.

Can I use old apache solr indexed data after upgrading apache version?

I have updated the apache2 version form apache2.2.14 to apache2.4.7 and also apache-solr package form 1.4.x to 4.x.
Before upgradation, I have indexed all the content.
After upgradation, in apache configuration it showing 0% indexed.
is there any way to use old indexing?
Solr / Lucene only upgrades older index formats in smaller increments, so you'll have to at least stop by a 3.x release on the way to be able to use the 1.4 index formats.
I'd also recommend going from 4 to 5 as well, since you're already doing the upgrade now, and will be stuck in the past again if you don't do the 5.x upgrade as well (6.0 was just released).
My suggestion is to optimize for easy reindexing, and do that. You'll run into the same issue later, or after doing any major changes to your schema.
The index format is backward compatible between two consecutive major
Solr versions. So a Solr 3.x index is compatible with a Solr 4.x
index. However if you have a Solr 1.x index and want to upgrade to
Solr 4.x then you would need to first upgrade to Solr 3.x first.
upgrade between major Solr Versions
So you'll have to go via 3.x (as Mats says below) or reindex or use the IndexUpgrader tool on your index.

What Mono version to use

I'm starting a new project that'll require Mono and mod_mono to run under CentOS. There are two versions of Mono: the release which is 2.10.8, and the development branch, which is 3.0.7 as of today.
I'm wondering what would be the right version to start. Obviously the stable version would be my choice, but I'm not sure what Mono 3.0 adds that could be missing from 2.10. Note that the project will be ASP.NET 4.0, using MVC4.
What version would be recommended? The stable but older one (dates back from 19-Dec-2011!) or the more recent one?
Mono 2.10 supports ASP.NET MVC3, since you want to use MVC4, you'll have to use a later version.
More recent versions of Mono have solved a lot of issues in 2.10, including issues related to ASP.NET.
So you may want to go for a more recent version. I don't think stability will be an issue,
but you will have to perform proper tests to determine if the version you are using supports everything you are trying to do in your application.
Don't deploy to production without testing.
UPDATE: Correction, there is 'partial' MVC4 support in 2.10 and no support for async.
So while you might be able to use 2.10, your mileage may vary depending on what features your app uses

Apache Solr which version to download 3.6.2 or 4.0, what is the main difference

There are 2 versions of Apache Solr on their official website 3.6.2 and 4.0:
http://lucene.apache.org/solr/downloads.html
What is the main difference, how to choose one?
Just get 4.0. It is a significant improvement over the 3.6.2 with a new Admin UI, support for lots of new options and a completely new SolrCloud distributed search mechanism.
If you are starting out, there is no point of going with the old.
The only thing is, 4.1 is about to be released. With a couple more improvements. So, download 4.0 today and 4.1 next week. Or just wait a couple of days and get it then.
