I have installed Apache Hadoop 2.6.0 in Windows 10. I have been trying to fix this issue but failed to understand the error or any mistake from my end.
I have set up all the paths correctly, Hadoop version is showing the version in command prompt properly.
I have already created temp directory inside hadoop directory like c:\hadoop\temp.
When I am trying to format the Namenode, I am getting this error:
C:\hadoop\bin>hdfs namenode -format

I'm trying to do a hadoop installation.
I am following this article for hadoop installation instructions. One of the steps I need to do is to format the hadoop file system using the command:

I got the following error

I think you have to fix the "description" tag. There is no proper end.

Any idea on what is going wrong?
exitCode: 1639 Looks like your are running hadoop on Windows .
https://github.com/OctopusDeploy/Issues/issues/1346
I faced exactly same problem. I was following a guide on how to install Hadoop 2.6.0 (http://www.ics.uci.edu/~shantas/Install_Hadoop-2.6.0_on_Windows10.pdf) while actually installing Hadoop 2.8.0.
As soon as I was done I ran
hadoop jar D:\hadoop-2.8.0\share\hadoop\mapreduce\hadoop-mapreduce-examples-2.8.0.jar wordcount /foo/bar/LICENSE.txt /out1
And got (from yarn nodemanager's logs):
17/06/19 13:15:30 INFO monitor.ContainersMonitorImpl: Starting resource-monitoring for container_1497902417767_0004_01_000001

ExitCodeException exitCode=1639: Incorrect command line arguments.
TaskExit: error (1639): Invalid command line argument. Consult the Windows Installer SDK for detailed command line help.
Another symptom was (from yarn nodemanager's logs):
17/06/19 13:25:49 WARN util.SysInfoWindows: Expected split length of sysInfo to be 11. Got 7
The solution was to get compatible (with Hadoop 2.8.0) binaries: https://github.com/steveloughran/winutils/tree/master/hadoop-2.8.0-RC3/bin
Once I got a correct winutils.exe, my problem went away.
I've checked multiple posts with the same questions, and the solution is always adding the following to the yarn-site.xml
<?xml version="1.0"?>

I covered both properties in the config and restarted yarn. The problem still remains.

I was hoping for a typo but can't seem to find it. Tried directly copy what's on stackoverflow into the xml file, still doesn't work.
What else can I try?
EDIT:
Since the error says the aux_service should be auxService, i modified the yarn-site.xml according, changing all aux-service to auxService, but it's still not working.
EDIT2:
In case anyone's interested, I call this command
hadoop jar hadoop-streaming-2.7.1.jar \
-input /user/myfolder/input1/* \
-output /user/myfolder/output1 \
-mapper <path>/<to>/<mapper>/mapper.py \
-reducer <path>/<to>/<reducer>/reducer.py
while I'm already in /usr/local/cellar/hadoop/2.7.1/libexec/share/hadoop/tools/lib/
EDIT 3:
I'm a dumbass. proof-read the script guys!
Update the property name in yarn-site.xml as yarn.nodemanager.aux-services,
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
Using this link ,tried installing Hadoop version - 2.2.0(single node cluster)in ubuntu 12.04(64 bit machine)
http://bigdatahandler.com/hadoop-hdfs/installing-single-node-hadoop-2-2-0-on-ubuntu/
while formatting the hdfs file system via namenode using the following command
hadoop namenode -format
when i'm doing that ,getting the following issue,
14/08/07 10:38:39 FATAL namenode.NameNode: Exception in namenode join
java.lang.RuntimeException: org.xml.sax.SAXParseException; systemId: file:/usr/local/hadoop/etc/hadoop/mapred-site.xml; lineNumber: 27; columnNumber: 1; Content is not allowed in trailing section.
What shall i need to do inorder to solve the following issue?

Probably some caracter in your XML that you forget to erase. Please post your full XML. Like #Abhishek said!
I've created a few ebs filesystems on ec2 to use with hadoop. I've set the JAVE_HOME in the hadoop environment. But when I go to format the first volume it aborts with the following message

Does anyone have any idea why this error is happening or how to get around the problem?
Unfortunately in 1.x the format command's prompt is case-sensitive. Answer with a capital Y instead and it won't abort.
