ctubbsii opened a new issue #1665:
URL: https://github.com/apache/accumulo/issues/1665
As mentioned on #1662, the new property
`tserver.compaction.major.service.default.planner.opts.executors` overrides any
user-specified value in the now deprecated
`tserver.compaction.major.concurrent.max` property.
My proposed solution is:
* Change the default value of the old property to: `0`
* If the old property is not configured to its default value, then it must
be overridden by the user, in which case, we should:
* Infer the user wishes a single thread pool like:
`[{"name":"deprecation-inferred-single-pool","numThreads":"X"}]`, where `X` is
the value configured in the old property, and
* Issue a warning that the old property is deprecated and to show the
inferred value for the new property.
* If both properties' default values are overridden, then we should:
* Use the new property's value, and
* Issue a warning about the old one being set and show the new property's
value that will be used.
* If only the new property, or neither, or overridden from their default
values, then the new value will be used with no warnings.
