HTTPS HDFS failed, "unable to find valid certification path to requested target"

[#1]

I've followed steps for each host in https://community.hortonworks.com/articles/52875/enable-https-for-hdfs.html, to enable https for hdfs. Now, I can't enter Files View UI in Ambari and I don't know what problem. Can anybody help me to find a solution？ Thanks.

You will need to make sure that you imported the HDFS certificates to ambari server truststore.

You can refer to the following doc to know more about it:

https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.2/bk_ambari-security/content/set_up_truststor...

Choose Option [4] to setup truststore and then next time choose option [5] to import HDFS certification to ambari truststore.

# ambari-server setup-security
.
.
[4] Setup truststore.
[5] Import certificate to truststore.
