@renuu this should be the correct format for a $_GET request to the service:   https://localhost:8080/api/alarm?sort-by=from-date=${lastTime} However, are you sure this is the correct Remote Url?  I see maybe an issue with sort-by=from-date=... Maybe this should be sort-by=SomeValue&from-date=${lastTime}.  I also suspect the dashes (-) in the variable names as this is not a good practice in variable naming.   What is the service you are trying to get the alarm from?  If its private can you PM me the details.     There are 4 ways to pass data from NiFi to InvokeHttp:   In the Remote Url as $_GET like above using format: ?value1=1&value2=2 In the body of the flowfile content, for example $_POST of json In Cookie using "Attributes to send" (pick an existing attribute). In Cookie using + (Add) property  Based on the service's requirements, you will need to handle invokeHttp to suit the requirements. ... View more

After you posted this new issue, I created a sample like yours, and I had the same error you have above.  Then I added the DistributedMapCacheServer, enabled it, and re-tested my flow.   I created a template for DetectDuplicate which you can find here:   https://github.com/steven-dfheinz/NiFi-Templates/blob/master/DetectDuplicate_DistributedMapCache_Demo.xml   If you install the template, you still have to + ADD the Map Cache Server in the Template's Process Group Controller Services.  The NiFI Template system does not include the server (known bug), it only includes the client.   ...

@renuu The solution you are looking for is to add the DistributedMapCacheServer from the controller services tab.  Set this to the same port as the DisitributedMapCachClient.   Enable. Test flow again.     If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.

@Udhav  Yes.  Permissions very user specific.  Can you create separate scratch locations for the user?  They would need to be chown correctly to the user and writeable chmod 777.  Right now that /tmp/hive is hadoopuser:supergroup. ... View more

@renuu  Try the DistributedMapCacheClient Controller Service,  not Redis (unless you have a redis system you can use).  If you use the other one you can set it to localhost and work within NiFi.   After creating the  DistributedMapCacheClient be sure to click + and add DistributedMapCacheServer to run on the same port.    Here are some screen shots of my sample:   DetectDuplicate:   DistributedMapCacheClient:   DistributedMapCacheServer:         Additionally,  when working a demo flow,  be sure to always route the other relationships during testing (detectDuplicate).  You do this so when its running you can see the duplicate or non-duplicate outputs.   If you run the flow, and it doesn't work as expected you will see where it went, then can adjust.    For example, below is how I use an output port to hold all the routes for InvokeHttp.  Later when I know it works, I will auto terminate what I don't need, and route what I do need.     Last but not least, spend some time in the community doing research to learn from other examples for your Use Case by searching the community:   https://community.cloudera.com/t5/forums/searchpage/tab/message?advanced=false&allow_punctuation=false&filter=includeTkbs,location&include_tkbs=true&location=tkb-board:CommunityArticles&q=distributedmapcache     If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.
