I am new to Apache Pulsar and I am trying to recover from a situation. To start with I have Lucidworks Fusion running on Amazon EKS. Fusion uses Apache Pulsar as their distributed messaging platform. While upgrading the version of Fusion I seem to have corrupted ledger data and since I am unable to get Fusion running again. Indeed nearly all pods in this cluster are dependent on Pulsar, more specifically bookkeeper pods and since bookkeeper can not startup given the corrupted ledgers the pods remain in a CrashLoopBackOff state and Fusion remains down. Here is the error in the bookkeeper pod logs:

Is there a way that I could fix this ledger data ?
If fixing this ledger data is not possible how can I clear/flush all data out of Pulsar and start fresh, re-initialized Pulsar of sorts ?
