简而言之,当 Elasticsearch 中恢复快照文件的过程被中断或取消时,会出现此错误。这可能是由于多种原因造成的,例如网络问题、磁盘空间不足,或 Elasticsearch 集群处于高负载状态。要解决此问题,您可以尝试以下方法:1) 确保足够的磁盘空间和网络稳定性,2) 检查 Elasticsearch 集群的负载并在必要时降低负载,3) 重试快照恢复过程,以及 4) 检查 Elasticsearch 日志中是否存在任何潜在问题。
日志上下文 #
日志 “Recover snapshot files cancelled” 的类名是 RecoverySourceHandler.java. 我们从 Elasticsearch 源代码中提取了以下内容,供那些寻求深入上下文的人参考:
// valid; it means that some of the snapshot files download failed and the snapshot files
// differ from the source index files. In that case we have to cancel all pending operations
// and wait until all the in-flight operations are done to reset the recovery and start from
// scratch using the source node index files.
assert this.cancelled.get();
throw new CancellableThreads.ExecutionCancelledException("Recover snapshot files cancelled");
