David Radley commented on ATLAS-2270:
-------------------------------------
[~ppadovani] - as far as I am aware there is no one working on this at the
moment. The only permutation that works is the Hbase solr one at the moment in
master. You could become a contribute and contribute a fix, which we could
commit. I think in these situations the person who would like it in, needs to
contribute the fix and would then fix any issues in that stack. At this time ,
this stack is not a priority at the moment for the few committers I have talked
to. Is this patch something you want to contribute i.e. provide a patch to
master and submit on the review board and be up for fixing any issues in that
stack. I so I could commit it for you if it does not break the hbase solr
config.
> Supported combinations of persistent store and index backend
> ------------------------------------------------------------
>
> Key: ATLAS-2270
> URL: https://issues.apache.org/jira/browse/ATLAS-2270
> Project: Atlas
> Issue Type: Bug
> Reporter: Graham Wallis
> Priority: Major
>
> We need to discuss and decide which combinations of persistent store and
> indexing backend Atlas 1.0.0 (master) should support. This includes
> building/running Atlas as a standalone package and running UTs/ITs as part of
> the Atlas build.
> This JIRA focusses on titan0 and janusgraph 0.2.0, as they are the graph
> databases that will be supported in master/1.0.0. This JIRA deliberately
> ignores titan1 and janusgraph 0.1.1 as the former should be
> deprecated/removed and the other is a transient state as we get to janusgraph
> 0.2.0.
> With titan0 as the graph provider, Atlas has supported the following
> combinations of persistent store and indexer. It is suggested that this set
> is kept unchanged:
> {{
> titan0 solr es
> ------------------------------------
> berkeley 0 1
> hbase 1 0
> cassandra 0 0
> }}
> With janusgraph (0.2.0) as the graph provider, Atlas *could* support
> additional combinations. Cassandra is included in this discussion pending
> response to ATLAS-2259.
> {{
> janus 0.2.0 solr es
> ------------------------------------
> berkeley ? 1
> hbase 1 ?
> cassandra ? ?
> }}
> It is suggested that the combinations marked with '1' should be continued and
> the remaining 4 combinations, marked with '?', should be considered. There
> seems to be evidence of people using all 4 of these combinations, although
> not necessarily with Atlas.
> Depending on the decision made above, we need to ensure that it is possible
> to build Atlas as a standalone package with any of the combinations - i.e.
> that they are mutually exclusive and do not interfere with one another. They
> currently interfere which makes it impossible to build Atlas with
> -Pdist,berkeley-elasticsearch because the 'dist' profile will exclude jars
> that are needed by the berkeley-elasticsearch profile - which leads to class
> not found exceptions when the Atlas server is started. The solution to this
> could be very simple, or slightly more sophisticated, depending on how many
> of the combinations we choose to support.
