Review comment:
would this delete data from table whose name has `tmp-` prefix? because
table segments are put under dir like `<dataDir>/<tableNameWithType>/...` as
initialized
[here](https://github.com/apache/pinot/blob/master/pinot-segment-local/src/main/java/org/apache/pinot/segment/local/data/manager/TableDataManagerConfig.java#L79):
```
defaultConfig.addProperty(TABLE_DATA_MANAGER_DATA_DIRECTORY,
instanceDataManagerConfig.getInstanceDataDir() + "/" +
tableNameWithType);
```
