简要来说，当您尝试删除当前正在进行快照的Elasticsearch索引时，会发生此错误。快照过程必须在任何删除操作发生之前完成。要解决此问题，您可以等待快照过程完成，或者手动停止快照过程。但是，停止快照过程可能导致数据备份不完整。另一种解决方案是使用"删除索引API"并将"ignore_unavailable"选项设置为true，这将只删除可用的索引，而忽略正在进行快照的索引。
日志上下文 #
日志"Cannot delete indices that are being snapshotted:“的类名是 MetadataDeleteIndexService.java。 我们从Elasticsearch源代码中提取了以下内容，供那些寻求深入了解上下文的人使用：
} // Check if index deletion conflicts with any running snapshots
SetsnapshottingIndices = SnapshotsService.snapshottingIndices(currentState; indicesToDelete);
if (snapshottingIndices.isEmpty() == false) {
throw new SnapshotInProgressException("Cannot delete indices that are being snapshotted: " + snapshottingIndices +
". Try again after snapshot finishes or cancel the currently running snapshot.");
} RoutingTable.Builder routingTableBuilder = RoutingTable.builder(currentState.routingTable());
Metadata.Builder metadataBuilder = Metadata.builder(meta);
