Hi @rajivswe_2k7,   Alternatively, you can run your FlowFile through a ReplaceText processor and configuring it with replacement value of "ravi" / replacement strategy of "append" and Evaluation mode of "Line-by-line"   ... View more

Hello  @jdelarosa91,   First off welcome to Apache NIFI and its ecosystem.   You can accomplish this by using PutDistributedMapCache and FetchDistributedMapCache processors. First, you must configure the DistributedMapCacheServer and DistributedMapCacheClientService controller services. Then your dataflow should be like so:   Get token: InvokeHttp > UpdateAttribute ( Assign an attribute for instance MyToken and give it value TOKEN ) > EvaluateJsonPath ( get the value you want ) > PutDistributeMapCache ( For cache entry identifier give it the attribute ${MyToken}  )   Now in the MapCache we have a key, value like so: TOKEN / <the string you got from EvaluateJsonPath>   And when you need to grab the token:   GenerateFlowFile ( Configure an attribute MyToken give it value of TOKEN ) > FetchDistributeMapCache ( cache identifier ${MyToken} and "out identifier in attribute" give it a name to call your token with) > InvokeHttp ( Here when you need to use the token you can call it using nifi attribute ${the attribute with the token retrieved from you MapCache )     ...

hmm to me it sounds like you have a DNS issue. I would go to the logs directory of one of the NIFI hosts: If using HDF it should be:   /usr/hdf/current/nifi/logs   and then do a grep like this:   grep "org.apache.nifi.web.server.JettyServer" *   One of the very last lines should have something that reads like so: nifi-app_2019-07-25_13.0.log:2019-07-25 13:30:40,076 INFO [main] org.apache.nifi.web.server.JettyServer NiFi has started. The UI is available at the following URLs: nifi-app_2019-07-25_13.0.log:2019-07-25 13:30:40,076 INFO [main] org.apache.nifi.web.server.JettyServer http://SOME-URL:SOME-PORT/nifi   Once you have that then I would try to ping that FQDN or IP and if you cant then you either have something going on with DNS or need to add that FQDN and IP to your local machines /etc/host file, assuming you are trying to reach the UI on a *NIX machine ...

Hi, Where is NIFI running? Is it on your own machine or somewhere else? By default and if using HDF, if NIFI is not secured it will run on port 9090 but if you are secured it will run on port 9091. Do you have a value on your machine in file /etc/hostname? on one of your nifi nodes?   I assume you are deploying HDF? ... View more
