Hey Aaron. Thank you for your answer.
Ok for the moment the solution I'm trying is to replace the libs httpcore-4.2.5 and httpclient-4.2.5 in the oozie folder of the oozie sharelibs by the version 4.4. My workflow ended successfully. I'm doing additionnal tests with the other workflows that I have on my cluster to see if they are impacted. To the Oozie developpers, may you help me on this topic please ? Best regards. Morgrim.
