-----------------------------------
{quote}This patch can work only with Spark versions < 2.4 without
{{spark.ui.proxyBase}} set
{quote}
[~mgaido] - if this patch works with an older version of spark then this is
exactly why our service definitions support versioning.
We should create a newer version and allow this existing one to be explicitly
referenced by version in the topology thus preserving the behavior in < 2.4
based deployments. When a version is not indicated in the topology the latest
should be used.
In case it is unclear as to how to create a new version, you only have to
create a new version named directory inside the
\{gateway_home}/data/services/sparkhistoryui directory. As you can see, the
existing one is called 1.4 which is indeed less than 2.4.
This seems a very appropriate case for a new version to me.
Now, if this patch actually breaks versions less than 2.4 then we can certainly
talk about reverting or fixing it.
