Hello
You should give some information otherwise the problem statement is too
generic.
Information such as Ignite version, JVM version, JVM memory parameters, and
Docker deployment resources limits are required.

Please refer to the latest version, 2.9.0 is pretty old.
Have a look to the section about security for the REST APIs, on the same
documentation page.

Hello Arunima
I suppose you run Spark in containers so you can create a custom Docker
image to start Apache Ignite.
You can also start the server nodes programmatically by Java code.

Hello
It might be a number of things starting from no space available on your
disk, partition, and/or permissions and/or other constraints on your
workstation imposed by your organization.
I suggest you check this with your internal support team to exclude any
permission issue on your development

Hello
It's very strange that this method does not exist in the H2 library.
Can you please check you're not including the H2 library twice?
For what I know, Ignite works with h2-1.4.197.jar which is included in the
last bundle.
I think you are including a newer version instead, or aside.
Cheers
Hello
I am also using Apache Ignite for some projects, but I don't see any
dependency on h2 in my projects.
I think h2 dependency is coming from somewhere else.
Can you run a "mvn dependency:tree" and share the results?

Unfortunately reiterating the question won't help.
If you have no positive answer in days, it means there's no such features
in the making.
Also this is a community-based mailing list, it's not a commercial support

If running in a shared cloud environment, you should put best security
practices in place to secure all of your servers from connections from
unknown hosts (iptables rules) especially on sensitive ports as databases

I usually add iptables rules on top of every deployment, to block access

I usually deploy on more servers, but just 2 to 4, I don't have larger

Hello
I don't know if I can help you, but I'll give it a try, as I had problems
for slow startup time in the past, and I solved them.
Can you share a couple of information about JVM?
Which JVM version are you using on the two different setups?
Which JVM params are you using for them?
Thank you

I had a look at your logs and
Hello
It happened to me on a few occasions.
I have a couple of suggestions which may, or may not, solve your problem.
Please try :)
First, please ensure you use /dev/urandom as an entropy source.
/dev/random does a better job, but may cause long pauses (10 minutes or
longer may happen easier

Hello Kumar
It seems a problem similar to the one I had in the past.
Please check that you are running the JVM *without* the
"-XX:+AlwaysPreTouch" parameter.
Also, in my experience, using /dev/random as entropy source could block
startup for long time, hence I prefer using /dev/urandom

think it would be fixed by using the internal IP addresses.

Hello
For what I know, Apache Ignite does not allow different versions to run on
the same cluster.
I think that GridGain commercial version has support for running nodes with
different versions on same cluster.

Hello Loredana
You can switch to OpenJDK 8, which would be supported also for security
updates by all the major Linux distribution.
OpenJDK is production ready since years, actually Oracle's JDK is now a
build of OpenJDK, with some additions.

Hello
In my case of slow startup, as suggested from a member of this mailing
list, I deleted the -XX:+AlwaysPreTouch command line option from JVM
launch, and the cluster got back to very fast startup.
Don't know if you are using this option, hope it helps.

I think that the only supported version is Java 8 right now, and Java 11
