Re: Regarding Nifi packaging and deployment

The NiFi Expression language (EL) can also use system user environment variables as well as NiFI JVM properties as input. So you could create templates that have EL statements that reference these environment variables which would allow each system running the same dataflow to pull in different

Re: Facing Issue while connecting with HDFS

Digvijay, Are you talking about Kerberos authentication to the HDFS cluster? If so, in nifi.properties you specify your krb5.conf file: nifi.kerberos.krb5.file=/etc/krb5.conf (or wherever your conf file is) This is the file that would have your realms defined. Then on the HDFS processors

Re: Questions about the ordering of the FlowFile.

Paresh, You might want to look at the PriorityAttributePrioritizer[1]: *PriorityAttributePrioritizer*: Given two FlowFiles that both have a "priority" attribute, the one that has the highest priority value will be prprocessed first. Note that an UpdateAttribute processor should be used to

XML Questions

Hi I have two questions which I think may require bespoke processors. 1)  I have extracted a set of  values from xml tags and made them into flowfile attributes, how a can I add these flowfile attributes to one or more flowfiles? 2)  I have multiple xml files which I need to merge into one xml

Moving BinFiles

In NIFI-305, we refactored a parent class for MergeContent so the binning functionality could be reused. In practice, this isn't quite useful yet, because BinFiles is still in the nifi-standard-processors, which contains an org.apache.nifi.processor.Processor file. Therefore, any processor that
