Joseph Witt commented on NIFI-1544:
-----------------------------------
Hello
Ignore my guidance about ${date} - that was definitely wrong.
I've attached a template that I believe follows what you were trying to do and
a sample input file. I was able to validate that the correlation attribute
(date) is retained after the merge.
I'm going to close this ticket out but happy to keep the conversation going.
Thanks
Joe

> URL: https://issues.apache.org/jira/browse/NIFI-1544
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 0.4.1
> Environment: unix, nifi-0.4.1 compiled with hadoop-2.4.0
> Reporter: Shekhar Bansal
> Priority: Minor
>
> My workflow:
> ListFiles
> FetchFIles
> SplitFIles
> ExtractText - Extract "date" from records
> MergeContent - Correlation Attribute=date
> UpdateAttribute - outputDirecoty=/data/output/${date}
> PutFile
> Problem is date is not available in UpdateAttribute processor.
> Since all the records in a particular flow have same date, it should be
> available in UpdateAttribute processor.
> Because of this issue I have to read merged flow again(only first record).
