# [FAQ] Lightning 导入非空集群报错 RocksDB Operation aborted

## Key Words

Lightning, RocksDB Operation aborted

## Description

使用 Lightning 导入非空集群报错，示例： 

```log
[ERROR] [tikv.go:161] ["compact cluster failed"] [level=-1] [tikv=xxx.xxx.xxx.xxx:xxxxx] [takeTime=2m31.380964905s] [error="rpc error: code = Unknown desc = Engine(\"[src/import/sst_service.rs:412]: RocksDb Operation aborted: File /37846393.sst that has overlapping key range with one of the compaction  input file is currently being compacted.\")"]
[ERROR] [restore.go:293] ["run failed"] [step=4] [error="rpc error: code = Unknown desc = Engine(\"[src/import/sst_service.rs:412]: RocksDb Operation aborted: File /37846393.sst that has overlapping key range with one of the compaction  input file is currently being compacted.\")"]
```

## Content

由于 lightning toml 配置文件中配置了 compact 参数，导致报错。取消配置文件中的 compact 参数配置即可。

```toml
[post-restore]
level-1-compact = false
compact = false
```
