Troubleshooting Object Copier Hub (OCH)

Copy operation times out or fails

If /opt/mapr/logs/och.log contains a time-out entry for the copy operation using the Object Copier Hub, check the time on both the source and destination nodes (whether AWS or Data Fabric). If the time is not in sync, the source and destination nodes must be time-synced.

Run the following command to set the time on the source and destination nodes to the time of other machine.

sudo date -s "$(ssh user@<other-machine-ip> 'date-Ins')"

Note: In case copy is failing with timeout issues, run this command to sync the time on both machines.

TLS handshake issues

During the copy operation if you encounter TLS handshake error, verify the proxy settings in mapr-och.service file. Check if these variables have been correctly set.
