Hey Guyz,
I have tried to install and configure wire encryption on 2 node hdp2.2 cluster using self signed certificates as per http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.6.0/bk_reference/content/ch_wire6.html however my sample mapreduce job getting failed during encrypted shuffle phase ( please note that I can run only map tasks not reduce tasks as job gets failed during shuffle phase ). Also, I can access namenode, resource manager etc. UIs via HTTPS.
Error :

To avoid above error and as per http://stackoverflow.com/questions/3775483/ssl-handshake-exception I exported certs to java’s cacerts file however now getting below error.
Error after exporting files to java’s cacerts file :

Please note that – I was able to setup and configure wire encryption using same steps in 2 node clusters using self signed certs on hdp 2.1 however facing above problem in hdp2.2.
Please help help help!
Thanks in advance.
