maxMergeSizeForForcedMerge default is negative
[ https://issues.apache.org/jira/browse/SOLR-7163?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Toke Eskildsen updated SOLR-7163:
---------------------------------
Attachment: SOLR-7163.patch
Simple patch that divides the default value with 1024 two times to compensate for later multiplying with 1024 * 1024.

> The default value for `maxMergeSizeForForcedMerge` in the class `LogByteSizeMergePolicy` is `Long.MAX_VALUE*1024*1024` which overflows and becomes -1048576.
> As far as I can see this results in forced merges always failing to merge, but frankly this is so far from my area of interest that I will not take the time to create a proper unit test.
