Hello,
The maintenance work was completed successfully without incident.
Ingestion into the data lake has recommenced and all HDFS datasets are
back-filling now, so no gaps in data are expected as a result of this
operation.
Kind regards,
Ben

Hello,
This is a brief reminder that HDFS will be put into safe mode in
approximately 1 hour from now.
The YARN scheduler queues will also be set to a STOPPED state for the
duration of the switch upgrade.
I'll send out a further message once the work has been completed.
Kind regards,
Ben
