@Omarb   Not sure if this is helpful, but sometimes I do something like this:    Take the operational test, write the schema, then capture it from one of your tests (check attributes for the schema).   Now re-use that schema object for the non-operational test instead of infer-schema.    I only like to infer schema to help me write the schema, especially if complicated.   Hope this helps,   Steven ...

@shashikumar Although I do not recommend this, due to creating confusion, you certainly can symlink the file paths on any linux system.   Just be sure the permissions are correct on the final new path, then create the symlink back to the old paths. ... View more

In windows are you able to connect to gmail/imap using email client?    Assuming nifi is on windows, that may be a test.   I still think there are things needing to do on gmail side to allow.   The imap port needs to be whatever port gmail provides.  I assume it is 993 from above.  Another port will not resolve connectivity issue, unless 993 is the wrong port alltogether. ...

@sayak17 Do you have connectivity to port 993 from nifi host to gmail host?   Test this with telnet to ensure network is connecting.   If not, check nifi host firewall, etc.  After this if still cannot connect, there may be gmail settings you need to enable to allow connectivity. ... View more

@Nifi_Al Its hard to guess here without seeing your flow, but i think here are a few ideas to resolve:   Use GenerateFlowFIle with content of the json you want to send to PutElasticsearchHttp Use AttributesToJson to write attribute to content of flowfile, then send that to PutElasticsearchHttp   To test basic connectivity, i would use the first method, then build a working flow from there.  I always work in small operational samples when trying to figure out how to configure a certain processor. ...

@rangareddyy You will need to add attributes to the flowfile: flowFile = session.putAttribute(flowFile, 'myAttr', 'myValue') Reference:   https://community.cloudera.com/t5/Community-Articles/ExecuteScript-Cookbook-part-1/ta-p/248922 ... View more

This is a groovy error.  I would suggest having a working groovy script executeable outside of nifi before trying to modify and execute that code in the context of ExecuteScript. ... View more
