@ChickenSoup76 Is Dremio up and running? Also you can just add the below support key and set how many days you want job history,

jobs.max.age_in_days

Other option is to shutdown Dremio and run the below command

bin/dremio-admin clean -j 10

The above command will clean job > 10 days but only once, default will still be 30 so the support key option a permanent change

@balaji.ramaswamy Oh,thank you.It helps a lot. I already fix my problem.As you say,Dremio is up and running when I execute those code, It cause the RocksDBException. I have one last question,Is that the support key only effective in the cluster mode ? I try to modify jobs.max.age_in_days as 7 on my Dremio running in single mode , It seems like not work.

Thanks.

@ChickenSoup76 Should work on a single node, it will start to clean up in the background so may take a while versus the offline clean up is instant
