Yes i am following this http://hortonworks.com/blog/end-end-wire-encryption-apache-knox/ to make a call to HDFS through KNOX security using user name and password. When i make a call through REST API it is showing this error Unable to Connect to SSL Services due to PKIX Path Building Failed

Hi, I am trying to configure HDFS for SSL certificate and following the instructions on the document on End to End wire encryption with Knox. Not sure how to set these properties in Ambari UI. Any help would be appreciated. Thanks Use Ambari to set the following properties in core-site.xml. [code language=”XML”] hadoop.ssl.require.client.cert=false hadoop.ssl.hostname.verifier=DEFAULT_AND_LOCALHOST hadoop.ssl.keystores.factory.class=org.apache.hadoop.security.ssl.FileBasedKeyStoresFactory hadoop.ssl.server.conf=ssl-server.xml [/code] Use Ambari to set the following properties in hdfs-site.xml. [code language=”XML”] dfs.http.policy=HTTPS_ONLY dfs.datanode.https.address=workshop.hortonworks.com:50475 [/code] The valid values for dfs.http.policy are HTTPS_ONLY & HTTP_AND_HTTPS. The valid values for hadoop.ssl.hostname.verifier are DEFAULT, STRICT,STRICT_I6, DEFAULT_AND_LOCALHOST and ALLOW_ALL. Only use ALLOW_ALL in a controlled environment & with caution. And then use ambari to restart all hdfs services.
