[DISCUSSION] Complete Discontinuation of IGFS and Hadoop Accelerator

[dmagda]

I don't think it's required to wait until Ignite 3.0 to make this happen.
If I'm not mistaken, we stopped releasing Hadoop binaries and sources a
long time ago (at least you can't longer find them on the downloads page).
Also, we removed all the mentioning from the documentation and website.
Nobody complained or requested for a maintenance release since that time.
Thus, I would remove the integration in 2.9. If anybody shows up later then
they can use the sources in the 2.8 branch and do whatever they want.

Guys,

Any updates here? Looks like we still don't have a consensus about release
version for this patch (already mention it in the release thread).
Currently, the ticket is still targeted to 2.9.

Hi Alex,

It's been a year since we voted to discontinue this integration [1] and it
wasn't removed from the source code earlier only because of the internal
dependencies with the ML component. Now all the dependencies are gone and
Ignite 2.9 is the right version to finish the discontinuation process. It
would make sense to wait for Ignite 3.0 only there are some breaking
changes in the APIs that will stay in Ignite.

 @Anton Kalashnikov <[hidden email]>, you mentioned that you
removed some methods from the configuration. Could you please list them
here? Are they Hadoop-specific or generic?

[Anton Kalashnikov]

Hi,

All of these methods are from IgniteConfiguration:
Hadoop configuration:
- HadoopConfiguration getHadoopConfiguration()
- IgniteConfiguration setHadoopConfiguration(HadoopConfiguration hadoopCfg)

IGFS (Ignite In-Memory File System) configurations:
- FileSystemConfiguration[] getFileSystemConfiguration
- IgniteConfiguration setFileSystemConfiguration(FileSystemConfiguration... igfsCfg)

thread pool size that will be used to process outgoing IGFS messages:
- IgniteConfiguration setIgfsThreadPoolSize(int poolSize)
- int getIgfsThreadPoolSize()


Of course, I can leave these methods intact but they will be doing nothing so API formally wouldn't be changed but, in fact, features would be removed. Does it make sense? I don't think so and in my opinion, perhaps it is ok to remove these methods right now if we are ready to remove these features right now. (but again, if there are some concerns about it, I can easily to leave these methods with empty implementation)

Anton Kalashnikov

[Anton Kalashnikov]

Sorry, I was mistaken, we can not leave these methods because at least FileSystemConfiguration and HadoopConfiguration require corresponded classes that were deleted. So I think we should just remove it right now.

[dmagda]

The removal of these methods will not impact anybody during migration to
2.9. Unless you use the Hadoop Accelerator or IGFS in your application. In
the latter scenario, well, the integration has already been discontinued
and you need to clean your application code before moving forward to 2.9.
Anyway, it's highly unlikely that we have any users of the integrations,
otherwise, they would show up throughout the year after learning that the
integration is no longer supported and discontinued.

Pavel, do you still prefer us merging the changes in Ignite 3.0 or agree to
do that in 2.9?
