> Key: HDDS-2396
> URL: https://issues.apache.org/jira/browse/HDDS-2396
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: Ozone Manager
> Affects Versions: 0.4.1
> Reporter: Li Cheng
> Priority: Major
> Attachments: hs_err_pid9340.log
>
>
> Env: 4 VMs in total: 3 Datanodes on 3 VMs, 1 OM & 1 SCM on a separate VM, say
> it's VM0.
> I use goofys as a fuse and enable ozone S3 gateway to mount ozone to a path
> on VM0, while reading data from VM0 local disk and write to mount path. The
> dataset has various sizes of files from 0 byte to GB-level and it has a
> number of ~50,000 files.
>
> There happens core dump in rocksdb while it's occasional.
