note
Cloudera recommends that after decommissioning and deleting an OM node, you must manually delete the below-mentioned paths:
```
-> rm -rf /var/lib/hadoop-ozone/om/data/bootstrapfile
-> rm -rf /var/lib/hadoop-ozone/om/data/om/current/
```
In case of a secure cluster, delete these paths:
-> rm -rf /var/lib/hadoop-ozone/om/ozone-metadata/om/certs/ -> rm -rf /var/lib/hadoop-ozone/om/ozone-metadata/om/keys
