can anyone help me tpo get rid of this problem!
Check your Ports which are necessary to be opend for the connection between Radoop and RapidMiner. (NameNode, DataNode ...)
Is Hadoop running on the same system as RapidMiner or in a Cloud like Azure?
Can you as well share your logs with us so we can have a closer look?

Stopping Derby server...
Derby server stopped.
Any help would be great. Thanks!
1)Open a cmd and paste this :
MKDIR C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\servers\AdminServer\security
echo username=weblogic> C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\servers\AdminServer\security\boot.properties
echo password=YOUR_WEBLOGIC_PASSWORD>> C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\servers\AdminServer\security\boot.properties
MKDIR C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\servers\WLS_FORMS\security
echo username=weblogic> C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\servers\WLS_FORMS\security\boot.properties
echo password=YOUR_WEBLOGIC_PASSWORD>> C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\servers\WLS_FORMS\security\boot.properties
2)Open folder C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\servers\AdminServer\security.
And open the boot.properties file.
3)Enter your weblogic password and insure that there are no spaces after it.
Save the file and rerun your weblogic server
Hello this is santosh kumar and I have resolved the problem
Steps
Rename the file name "ldap" to "ldap_bkp"

Copy the location path of ldap field:
"C:\Oracle\Middleware\user_projects\domains\ClassicDomain\servers\AdminServer\data\"
Open command prompt in administration mode
it will open like this "c:\Windows\system32>" as bellow:
c:\Windows\system32> cd C:\Oracle\Middleware\user_projects\domains\ClassicDomain\bin press enter
c:\Windows\system32> cd C:\Oracle\Middleware\user_projects\domains\ClassicDomain\bin> set DomainEnv.cmd
c:\Windows\system32> cd C:\Oracle\Middleware\user_projects\domains\ClassicDomain> -- disappear bin

c:\Oracle\Middleware\user_projects\domains\ClassicDomain>cd servers\AdminServer\security
c:\Oracle\Middleware\user_projects\domains\ClassicDomain\servers\AdminServer\security>notepad boot.properties
It will open file in notepad if file is blanck write there password and username like. If contents availabale edit the user and password as new (see below) and then save and exit notepad:
password=weblogic123
username=weblogic
In the command prompt in administration mode type: C:\Oracle\Middleware\user_projects\domains\ClassicDomain\servers\AdminServer\security> cd C:\Oracle\Middleware\user_projects\domains\ClassicDomain\bin press enter
In the command prompt in administration mode type: C:\Oracle\Middleware\user_projects\domains\ClassicDomain\bin>startWeblogic.cmd press enter
It will run with default loging and password : weblogic/weblogic123.
I use a Oracle WebLogic Server 12c and when I start it on Eclipse it shows this error, it does'nt allow me to log in localhost neither when I try to access it
from another computer in a different domain, in the log appears that the server is not reacheable.
This is the exception that appears in Eclipse.

And this is my StartBt script file, used to start the server and specify some preferences:
nmConnect('weblogic','AXLWL20040','localhost','5521','base_domain','C:/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain','plain')
nmStart('AdminServer')
nmDisconnect()
I want to make it accesible, not only for local.
nmConnect('weblogic','AXLWL20040','localhost',**'5521'**,'base_domain','C:/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain','plain')
Port should listen to 5545.
You wrongly configure the ports. Your NodeManager listen on port 5540
ListenPort=5540
You try to connect to 5545

I made a setup to run selenium scripts during jenkins build. Jenkins is available in linux machine and selenium-server-standalone-2.39.0.jar is running in the jenkins machine.
The selenium grid will run the scripts in windows machine and the code looks like,
DesiredCapabilities desiredCapabilities = DesiredCapabilities.chrome();
desiredCapabilities.setBrowserName("chrome");
desiredCapabilities.setPlatform(Platform.ANY);
WebDriver driver = new RemoteWebDriver(new URL("http://example.com:5555/wd/hub"), desiredCapabilities);
I also have the below setup in jenkins,
maven is used to run the selenium test suite and the junit test report are published.
Sometime the jenkins machine is going down with the below error,

The problem is that, jenkins is going down when the selenium scripts got failed or sometimes when viewing the failed test results in jenkins test report.Can anyone please suggest why this issue is occuring and how to resolve this issue?
Is this issue occuring due to the selenium server running in jenkins machine or any other reason?
How to solve this error? Error occurred since I make master ip to public and assign DNS.

I have seen so many thread regarding this, but didn't get any answer properly.
I connected using headless slave agent and put HOST:PORT in advanced setting of configuration of slave. Master is linux and slave is windows 7.
From Comments:
=================================
Since you are having problems with the public IP & DNS, can you make sure that routing for the public IP and DNS is allowed on your network. Just to be sure this is not a firewall issue. Are you on a corporate network? In that case, your corporate firewall may be blocking certain ports on all IP addresses.
I have Selenium Grid 1.0.8 running well with the hub and several remote controls on the same machine. My testNG tests all run successfully.
When I start a remote control on a different machine, everything initially appears to be fine. The hub console shows the remote control to be available with the default environment "*firefox".
However, when I run the tests (still on the hub machine), the remote controls on the other box never work properly. They keep getting deregistered from the hub.
I've disabled the firewalls and I can ping betweeen the two boxes. Has anyone encountered similar issues?
The Remote Control Log:

Are you passing the correct host value when you register your node? In order to deal with proxies properly, the node must provide a routable hostname to that node when registering with the hub. Without this value, the hub will be unable to communicate with the node and will unregister it.
