service checks fails for YARN,PIG,HIVE,MR after enabling SSL for KMS. I followed following docs to enable the same:

http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.3/bk_security/content/ranger_kms_ssl.html

Ranger kms functionality works fine, i am able to connect to the ranger kms , list the keys and all. but like mentioned service check for the YARN,PIG,HIVE,MR fails due to following exception:

Note: I have already imported kms certificate in hadoop client truststore.

Could you check what certificates the client truststore contains?

keytool -list -v -keystore /path/to/hadoop-client-truststore

It is worth checking, what is the ssl certificate used by the server.

openssl s_client -showcerts -connect https://<kms_host>:9393

You can copy paste the pem content (from begincert to endcert) in a new file and check its content

openssl x509 -noout -text -in saved.crt

If you're using self signed certificates like in the docs, then this certificate (server) should be the same that is in the client trust store.

@amagyar this is the certificate used by kms:

* Server certificate:

* subject: CN=<kms_host>,OU=Unknown,O=Unknown,L=Unknown,ST=Unknown,C=Un...

* start date: Mar 06 12:00:07 2017 GMT

* expire date: Mar 01 12:00:07 2018 GMT

* common name: <kms_host>

* issuer: CN=<kms_host>,OU=Unknown,O=Unknown,L=Unknown,ST=Unknown,C=Un...

and this is the certifciate i imported into hadoop client truststore

keytool -printcert -file /etc/security/serverKeys/ranger-kms-trust_<kms_host>

Owner: CN=<kms_host>, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown

Issuer: CN=<kms_host>, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown

It was silly mistake from my side , there was a client truststore file with the same name at server keys location too and i was importing in that file , after importing the certificate to correct file it worked for me thanks!!
