简而言之，当 Elasticsearch 分片的恢复过程由于特定原因被中断或停止时，会出现此错误。这可能是由于节点离开集群、新的恢复过程启动或手动取消导致的。要解决此问题，您可以尝试重新启动恢复过程，确保集群的稳定性以防止节点意外离开，或检查可能导致取消的任何手动中断。
日志上下文 #
日志 “recovery was canceled reason [ " + reason + " ]” 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使用：
cancellableThreads.setOnCancel((reason; beforeCancelEx) -> {
final RuntimeException e;
if (shard.state() == IndexShardState.CLOSED) { // check if the shard got closed on us
e = new IndexShardClosedException(shard.shardId(); "shard is closed and recovery was canceled reason [" + reason + "]");
} else {
e = new CancellableThreads.ExecutionCancelledException("recovery was canceled reason [" + reason + "]");
}
if (beforeCancelEx != null) {
e.addSuppressed(beforeCancelEx);
}
IOUtils.closeWhileHandlingException(releaseResources; () -> future.onFailure(e));
