@Benjamin Bouret The invokeHTTP processor would require you to use a SSL context service when communicating with a secure (https) endpoint. The SSLContext service can be setup with only a truststore.jks if this is only a 1-way TLS connection that does not require client authentication. - You should be able to use openssl to get the complete public certificate chain from the target secured endpoint. From command line execute following command: Openssl s_client -connect <hostname>:<port> -showcerts - The return from this command will include one or more public certificates. each public certificate will start with and end with following: -----BEGIN CERTIFICATE----- ..... -----END CERTIFICATE----- - Copy each certificate including the above two lines and write each to separate file with a .crt extension. for example: CA-1.crt - Then import each of these public certificates in to the truststore you want to use in your SSLContext service as follows: # keytool -import -alias <unique Alias name 1> -file CA-1.crt -keystore truststore.jks # keytool -import -alias <unique Alias name 2> -file CA-2.crt -keystore truststore.jks etc... - Make your your NiFi service user can read this file where ever you decide to place on each of your NiFi nodes. - Thank you, Matt - If you found this answer addressed your question, please take a moment to login in and click the "ACCEPT" link. ...

Thank you for your answer, The second hash is performed after a PutHDFS and not a ListHDFS (I have edited my post, sorry for the mistake). If I understand you well, this check is not useful because PutHDFS and FetchFile processors are already able to catch corruption errors reliably? I would compare both hashes with NiFi expression language (:equals function) inside a RouteOnAttribute processor. ... View more

@mattclarke I'm having the same problem using "ScrollElasticSearchHttp" processor. Processor state shows one or more nodes of cluster, depending on situation, even when I've configured to "Primary Node only". Flowfiles have been duplicated on each added node. How can I solve the problem? ... View more
