I've just painstakingly followed detailed instructions on how to install Hadoop on Windows 10. I have set the *_HOME and PATH environment variables correctly. Hadoop is in the path as when I enter hadoop it seems to start running, but gives me this message:
\Hadoop\hadoop-3.1.3\bin\ was unexpected at this time.
I have just followed the installation instructions carefully twice, and both installations were identical, so I didn't make a mistake on the second installation, I hope.
What could this error message mean, and what can I do about it?

I am trying to run chainlink on my laptop. Everything works fine as far the make install step but I am having issues when I run the command chainlink help. I get an error message that says: command not found.
I believe I have followed the installation process as per the instructions on the repo.
I have tried to debug the issue but no luck so far. Tried what is advised in the previous post on the topic below but it does not fix the issue. I have checked my paths list and it has the correct path link listed.

I want to installed the hadoop(3.2) in my linux system which has installed the hadoop(2.7).When I execute hadoop , I can only get the information of hadoop 2.7 ,even if I change the environment variable. And the most confused thing is when I run echo $HADOOP_HOME , sometimes I can get the path of hadoop 2.7,sometimes hadoop 3.2. I hope someone can help me.

Can someone help on this? I am trying to get hadoop 2.2.0 version and got error message
$ bin/hadoop version
bin/hadoop: line 133: C:Java/jdk1.7.0_45/bin/java: No such file or directory
bin/hadoop: line 133: exec: C:Java/jdk1.7.0_45/bin/java: cannot execute: No such file or directory
I am trying to install single instance hadoop on windows 7/64.
I did install Cygwin64 and hadoop on "c/+1/Hadoop/hadoop-2.2.0"
JAVA_HOME is
$ echo $JAVA_HOME
c:Java/jdk1.7.0_45
Any idea will be more than welcome so feel free to fire up!
"C:Java/jdk1.7.0_45/bin/java" is neither a valid Windows path nor a valid cygwin path. So your JAVA_HOME is set incorrectly. Set it to the directory where you installed the JDK. Maybe you mean "/cydrive/c/Java/jdk1.7.0_45/bin/java". Using "where java" or "which java" might help a bit.
(opinion follows...)
In my experience trying to set up hadoop on windows using cygwin is a tough battle, and usually not worth the effort. When I have to develop on Windows machines I usually set up a virtual machine running Linux, and everything tends to go much smoother.
I've been trying to figure out this problem for a while now and I thought I'd ask it here on stackexchange in case somebody out there has tried this and successfully got it to work.
I'm trying to install a RAD webapp tool called AppFlower through Xampp for Linux.
I am also experiencing issues with the command below:
symfony afs:init
symfony: command not found
This is the final command used to start up the AppFlower Studio dev environment, but this command doesn't work.
I have tried using:
./symfony afs:init
Same error as above
php ./symfony afs:init
gives a php error saying it isn't installed, but this is Xampp for Linux, so that command won't apply
/opt/lampp/etc/php.ini ./symfony afs:init
it will give a permission denied error, but even with 'sudo' in front, it says 'command not found'
The solution posted on the appflower forum is for xampp itself, but the problem I have is that they use the php.exe command to run the 'symfony afs:init' command, which xampp for linux doesn't have. The closest thing I could think of was to use the php.ini file, but (as seen above) that doesn't work.
Hopefully somebody can assist regarding this issue.
Regards,
Note. The process to run appflower on a manual version of lamp (one in which php, mysql, apache are all downloaded separately) is a lot more complex and the xampp installation is supposed to be much easier (in fact it is) but at the last point of this installation, this 'symfony afs:init' command is the only problem.
If you are already using Linux, why not install AppFlower directly. It's pretty straightforward, maybe i lost something on the way, understanding why you use XAMMP for Linux.
