Hi, We have switched from 5.4 to 7.2.1 and we have started to see more issues with the replication. I think it may be related to the fact that a delta import was started during a full import (not the case for the Solr 5.4).
I am getting below error: XXX: java.lang.IllegalArgumentException:java.lang.IllegalArgumentException: Directory MMapDirectory@XXXXXXX\index lockFactory=org.apache.lucene.store.NativeFSLockFactory@21ff4974 still has pending deleted files; cannot initialize IndexWriter Are there more known issues with Solr 7.X and the replication? Based on https://issues.apache.org/jira/browse/SOLR-11938 I can not trust Solr 7.X anymore. How can I fix the "XXX: java.lang.IllegalArgumentException:java.lang.IllegalArgumentException: Directory MMapDirectory@XXXXXXX\index lockFactory=org.apache.lucene.store.NativeFSLockFactory@21ff4974 still has pending deleted files; cannot initialize IndexWriter " issue?
