@tang-hi Our Elasticsearch has migrated to Segment replication mechanism, so the code runing on the Primary shard and Replica shard is different. The replica shard will not construct `IndexWriter` any more. Thread A starts a primary shard with procedure below 1. Construct `ConcurrentMergeScheduler` 2. Consctruct `IndexWriter` Thread B start a replica shard with precedure below 1. Deserialize `SegmentInfos` from disk 2. Start a read-only SearcherManager In the first step, we will call `SegmentInfos#readCommit` to deserialize `SegmentInfos`, call stack below ``` at org.apache.lucene.index.IndexWriter.<clinit>(IndexWriter.java:6485) at org.apache.lucene.index.SegmentInfos.parseSegmentInfos(SegmentInfos.java:499) at org.apache.lucene.index.SegmentInfos.readCommit(SegmentInfos.java:364) at org.apache.lucene.index.SegmentInfos.readCommit(SegmentInfos.java:311) ``` -- This is an automated message from the Apache Git Service.
