hadoop - CDH 5.1 host IP address change -

-

I have a CDH 5.1 cluster with 3 nodes. We have installed it by using the Cloudera Manager Automatic installation. It was running perfectly until we changed a separate network and IP addresses. I tried the following steps 

  1 stopped service, Claudeira-sqm-server 2. service closed, cloudera-scm-agent 3. edit / etc / cloudera-scm-agent /config.ini 4. Change the server host to the new IP. 5. The restart service, cloudera-scm-agent, cloudera-scm-server   
 is not working.  
 Then I did not help even after changing the IPS directly in PostGrace SQL.  
 I found the following blog:  
 Obtaining the following error in the scm-agent log file  
  Protocol error: & lt; Protocol error for 127.0.0.1/RPC2: 401 unauthorized & gt;   
 is not working. Can anyone please change all the IP addresses safely in the CDH 5.1 cluster .....  
 Thanks, Amit   
 
 
 This priceless cloudera-scm-agent service is being prevented properly, please try,  
  $ & Gt; Ps -ef | Grep supervisord $ & gt; Mar-9 & lt; ProcessID & gt;   
 Then restart the agent again.  
  $ & gt; Service Cloudera-SCM-Agent Start

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
