Solutions

1. Add the missing <currentId> element to the SecretManager section of the fsimage XML.
2. Regenerate the fsimage XML with 'hdfs oiv' from a valid fsimage.

When it happens

Trigger: Thrown by oiv -r when the SecretManager section header of the fsimage XML lacks the <currentId> element.

Common situations: See trigger scenarios.
