Incremental Persist Failed -- Unable to delete file

Hi,

I’m not sure what’s causing this error:

2016-03-29T20:09:20,014 ERROR [metrics-2016-03-29T20:02:00.000Z-persist-n-merge] io.druid.segment.realtime.plumber.RealtimePlumber - dataSource[metrics] – incremental persist failed: {class=io.druid.segment.realtime.plumber.RealtimePlumber, interval=2016-03-29T20:02:00.000Z/2016-03-29T20:03:00.000Z, count=0}

I’m using the configurations and emit script from this github (https://github.com/gianm/druid-monitorama-2015)

Can anyone help?

Thanks a lot

Hi Thomas, does the file it is complaining about exist?

Oh I’m sorry, you were right. Sorry about that

@Fangajin Yang,
