It looks like `snap-uZyUEl-YT7eUBotTzsgM7g.dat` is missing in HDFS. It's hard to say why without more information though. Is there anything interesting in your log files (on any Elasticsearch nodes or the Hadoop namenode or data nodes)? Is it possible that someone manually deleted it from HDFS? Here is where that error comes from in the code: [elasticsearch/HdfsBlobContainer.java at v5.5.0 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/blob/v5.5.0/plugins/repository-hdfs/src/main/java/org/elasticsearch/repositories/hdfs/HdfsBlobContainer.java#L98). But that is a _very_ old version and that code looks different now. I would upgrade if at all possible.
