I install ambari 2.1 and try to install hdp 2.1 with my local hdp repo.

I install ambari server and ambari agent manually by using yum.

system version is centos 6.6 64bit version.

I can login ambari server correctly,but when I registe the ambari agent ,it was failed.

I check the ambari agent log in /var/log/ambari-agent/ambari-agent.log

it display:

INFO 2016-03-23 16:50:29,558 main.py:287 - Connecting to Ambari server at https://master.yunwei.test:8440 (192.168.18.204) INFO 2016-03-23 16:50:29,558 main.py:287 - Connecting to Ambari server at https://master.yunwei.test:8440 (192.168.18.204) INFO 2016-03-23 16:50:29,558 NetUtil.py:59 - Connecting to https://master.yunwei.test:8440/ca ERROR 2016-03-23 16:53:50,341 NetUtil.py:77 - [Errno 8] _ssl.c:492: EOF occurred in violation of protocol ERROR 2016-03-23 16:53:50,341 NetUtil.py:78 - SSLError: Failed to connect. Please check openssl library versions. Refer to: https://bugzilla.redhat.com/show_bug.cgi?id=1022468 for more details.

I search the keywords "[Errno 8] _ssl.c:492: EOF occurred in violation of protocol" by google.

but the pages told me that it was the problem of openssl .I upgrade the openssl version,but it still display in the log file.

I don't know how to slove it.

@Geoffrey Shelton Okot

In my another cluster,use openjdk is OK,so ,I don't think use oracle-jdk is necessary
