	Hi @yadir Aguilar ,
 
 
	i think you should have started the ambari-server using the command
 
 
ambari-server start
 
 
	In that case please use the command 
 
 
ambari-server status
 
 
	This is just how systemd works. For systemd to track a process it needs to be started with systemd.  
	If it is started outside systemd, it won't manage the process and the status will be "not started"
 
 
	E.g:
 
 
# valid flow
ambari-server start
ambari-server status
 
 
# valid flow
systemctl start ambari-server
systemctl status ambari-server
 
 
# invalid flow
ambari-server start
systemctl status ambari-server
 
 
	Please accept answer if this helps you :)

							 Andy\Amarnath,   My question was initially why my expected outcome was not working and why this other format did work. Along the way, I believe my question was answered, assuming my understanding is correct. I did't want to dive to deep as I thought it may be outside the scope of my initial post. Since the conversation has gone that way tho, Andy is correct.     I did not understand the difference between 1-way SSL and 2-way SSL. Using 1-way SSL (keystore only) all HTTPS connections are accepted regardless if the source is who we are expecting or not. Using 2-way SSL only HTTPS connections are accepted but now we must verify who the source is by authenticating with a private key & server certificate that can be authenticated by my truststore.  My use case for this knowledge, is we are promoting projects between our Dev & Prod clusters. I wanted to ensure we had the correct security in place to proceed. The developers are wanting 1-way SSL but I lacked the knowledge at the time to make it work and only had 2-way. They were upset because this required more data to be sent via REST protocol using 2-way.  Now that I understand each protocol, I will not allow to them proceed to Production with their architecture without 2-way SSL. Originally, I was simply ignorant of how to setup 1-way SSL, without understanding the security hole it would make.  Thank you both for your time and effort in reviewing this concept.

							 @amarnath reddy pappu, I followed these steps but when I login to ambari, it is successfully getting redirected to knox gateway and after i give credentials it goes to ambari ui and then coming back to knox gateway log in screen.      Could you please suggest.      Opened questions in community also: https://community.hortonworks.com/questions/242895/knox-sso-not-working-for-ambari.html

							 In the end, I created the new cluster with HDF 3.2.0.   With NiFi Registry made it very fast.  Thanks to all which tried to help.

							 This is applicable for CentOS7/RHEL6 - for CentOS7/RHEL7 please follow https://community.hortonworks.com/articles/188269/javapython-updates-and-ambari-agent-tls-settings.html  Upgrading to  jdk1.8.0_171 version disables some of the TLSv1_1 TLSv1 protocols and algorithms. With this only option is using TLS1_2 version but CentOS6/RHEL6 uses Python 2.6 and it does not support TLS1_2.  Agent-server communication would fail with below error.  WARNING 2018-04-24 16:35:10,989 NetUtil.py:124 - Server at https://***.***.***.***:8440 is not reachable, sleeping for 10 seconds...INFO 2018-04-24 16:35:20,990 NetUtil.py:70 - Connecting to https://***.***.***.***:8440/caERROR 2018-04-24 16:35:20,991 NetUtil.py:96 - EOF occurred in violation of protocol (_ssl.c:579)ERROR 2018-04-24 16:35:20,991 NetUtil.py:97 - SSLError: Failed to connect. Please check openssl library versions. 
  To workaround this problem you can tweak /usr/jdk64/jdk1.8.0_112/jre/lib/security/java.security file in Ambari server host to enable some of the algorithms.  From:  jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 1024, \
			    EC keySize < 224, DES40_CBC, RC4_40, 3DES_EDE_CBC  To:  jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 1024, \
			    EC keySize < 224, DES40_CBC, RC4_40  Please note that this is just a temporary workaround and it is recommended to Upgrade the OS version to use TLS1_2

							 @amarnath reddy pappu  @mqureshi, @Kuldeep Kulkarni, @Gerd Koenig, @Andrew Ryansmaple-mapreduce-job-error.txtmapreduce-error-in-hive-wiht-beeline.txt
We have enabled SSL/TLS on HDP cluster by following @amarnath reddy pappu blog :
https://community.hortonworks.com/articles/52875/enable-https-for-hdfs.html  and HDP documentation.
Almost all service opening on Https defined port. But Only issue we are currently facing is :     MAP
REDUCE JOBS ARE NOT LAUNCHING
We use hive through beeline connector.   While executing query we receive error :
WARNING: Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases.   Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask. java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty (state=08S01,code=1)  Tried a Sample Map reduce Job alone as well. That also got failed. Error is long so attaching here.
I would appreciate your help. 🙂
