Hi,
I am using Solr 7.5.0, and I came across this presentation (
https://www.slideshare.net/sematext/solr-search-engine-optimize-is-not-bad-for-you)
on Solr Search Engine: Optimize Is (Not) Bad for You.
>From Slide 59, it touch on the settings on reclaimDeletesWeight.
I have tried to follow their example and configured the following
TieredMergedPolicyFactory in my solrconfig.xml.
<mergePolicyFactory class="org.apache.solr.index.TieredMergePolicyFactory">
<int name="maxMergeAtOnce">10</int>
<int name="maxMergeAtOnceExplicit">10</int>
<int name="segmentsPerTier">10</int>
<int name="floorSegmentMB">10</int>
<int name="maxMergedSegmentMB">5000</int>
<double name="noCFSRatio">0.1</double>
<int name="maxCFSSegmentSizeMB">2048</int>
<double name="reclaimDeletesWeight">2.0</double>
<double name="forceMergeDeletesPctAllowed">10.0</double>
</mergePolicyFactory>
However, when I load in the configuration, I get the following error.
Caused by: java.lang.RuntimeException: No setter corrresponding to

What could be the reason that caused the error?
