Hoss Man created SOLR-4934:
------------------------------
Summary: Prevent runtime failure if users use initargs
"useCompoundFile" setting on LogMergePolicy or TieredMergePolicy
Key: SOLR-4934
URL: https://issues.apache.org/jira/browse/SOLR-4934
Project: Solr
Issue Type: Bug
Reporter: Hoss Man
Assignee: Hoss Man
Fix For: 5.0, 4.4
* LUCENE-5038 eliminated setUseCompoundFile(boolean) from the built in
MergePolicies
* existing users may have configs that use <mergePolicy> init args to try and
call that setter
* we already do some explicit checks for these MergePolices in SolrIndexConfig
to deal with legacy syntax
* update the existing logic to remove "useCompoundFile" from the MergePolicy
initArgs for these known policies if found, and log a warning.
(NOTE: i don't want to arbitrarily remove "useCompoundFile" from the initArgs
regardless of class in case someone has a custom MergePolicy that implements
that logic -- that would suck)
