Steve Rowe resolved SOLR-9229.
------------------------------
Resolution: Fixed
Assignee: Steve Rowe
Fix Version/s: 5.5.2
These failures were caused because as part of the SOLR-8621 commit included in
Solr 5.5.0, the {{solr.tests.mergePolicy}} sysprop (set by {{TestNRTOpen}} to
{{org.apache.lucene.index.LogDocMergePolicy}}) was ignored in the
{{solrconfig.snippet.randomindexconfig.xml}} included in
{{solrconfig-basic.xml}}:
{noformat:title=SOLR-8621.patch against
solrconfig.snippet.randomindexconfig.xml}
<!-- this sys property is not set by SolrTestCaseJ4 because we ideally want
to use
the RandomMergePolicy in all tests - but some tests expect very specific
Merge behavior, so those tests can set it as needed.
-->
-->
- <mergePolicy
class="${solr.tests.mergePolicy:org.apache.solr.util.RandomMergePolicy}" />
+ <mergePolicyFactory class="org.apache.solr.util.RandomMergePolicyFactory" />
{noformat}
This problem was rectified shortly thereafter by SOLR-8674 and committed to
branch_5x, but never backported to branch_5_5 (note that SOLR-8621 didn't have
to be backported to branch_5_5 because it was committed to branch_5x before
branch_5_5 was created). Since SOLR-8674 isn't mentioned in {{CHANGES.txt}} at
all, I failed to backport it to branch_5_5 in prepartion for the 5.5.2 release.
When I cherry-picked SOLR-8674 branch_5x commit onto branch_5_5, all of the
above seeds started succeeding, so I'm resolving this issue as fixed.
