Subject Re: nifi stale flow file
Date Thu, 05 Nov 2015 20:07:33 GMT
Question – After I moved the stale file and  recovered the cluster, how does it perform the
pending requests that were in pipeline ?
I am trying to understand if a instance crash in uneventful situation, how do I recover the
data or the flow state.

Thanks,
-Chakri

Mark Thanks, I moved to another directory to keep it as a backup.
I moved it back to flow.tar and cluster is back online. Make sense, I will make sure workflows
are stopped prior restart.

Thanks,

Subject: Re: nifi stale flow file

Chakri,

When the Cluster Manager sends a request to nodes and that request will change the flow, it
marks its flow as "stale"
until it hears back from the nodes whether or not the request was successful. So it appears
that you restarted while
a request was being replicated to the nodes.

Typically, the answer to this is to rename flow.tar.stale to flow.tar and restart the Cluster
Manager. If you simply remove
the flow.tar you are effectively deleting your entire flow, so be careful with that!

When you say you "moved the stale file" what do you mean? You renamed it, removed it, moved
to another directory to keep
it as a backup?

I take it back, server came up clean. Slave nodes fails to connect server with following error.

Subject: nifi stale flow file

Hi – I have a clustered setup with NCM and two slaves. After few days of stable work, I
tried to restart the server and it failed to come up with error:

" Failed to instantiate [org.apache.nifi.cluster.flow.impl.DataFlowDaoImpl]: Constructor threw
exception; nested exception is org.apache.nifi.cluster.flow.DaoException: Dataflow state file
'/usr/local/nifi/./conf/flow.tar.stale' must be current.”

I moved the stale file and it started clean. Any idea why I ran into stale file ?

Also, why was it landed in conf dir ?

Thanks,
-Chakri
