Nifi startup fails with EncryptionOperationNotPossibleException
Hi there,
I'm encountering the following error when trying to start Nifi, it's giving me this error after Nifi was killed abruptly due to CPU load issue. I can no longer start Nifi and not sure why that happened. Would appreciate any help please. Below are some logs:
Thanks in advance ..

Re: Nifi startup fails with EncryptionOperationNotPossibleException
Posted by Andy LoPresto <al...@apache.org>.
Ashraf,
Glad to hear it fixed it. I have an existing Jira [1] filed which would include strengthening the default sensitive key algorithm, but would also require creating a tool to seamlessly upgrade the encrypted values from the previous algorithm. This tool could also support migrating values encrypted with a different key when it is changed. I’m not sure it will go in 1.0 because of the amount of work remaining, but I will update the ticket with this note.

The error looks like Jetty cannot start because it cannot decrypt some value from the flow controller serialization (the flow.xml.gz file in $NIFI_HOME/conf/). This could be the proxy password, or a sensitive processor property like a key or password (specifically from your stacktrace, it does appear to be a processor property). Did the flow document change at all? Did you change the “nifi.sensitive.props.key” value in nifi.properties?

Re: Nifi startup fails with EncryptionOperationNotPossibleException
Posted by Ashraf Hasson <AH...@WindMobile.ca>.
Andy,
Thanks for your reply. I think I must have changed the file at an earlier stage indeed. Reverted the nifi.sensitive.props.key to an empty string and it came back up.
Thanks,

Ashraf,
Were the configuration values changed after the process shutdown? The error looks like Jetty cannot start because it cannot decrypt some value from the flow controller serialization (the flow.xml.gz file in $NIFI_HOME/conf/). This could be the proxy password, or a sensitive processor property like a key or password (specifically from your stacktrace, it does appear to be a processor property). Did the flow document change at all? Did you change the “nifi.sensitive.props.key” value in nifi.properties?
