I've recently installed Hadoop and am not able to create a new directory:

Error occurred during initialization of boot layer
java.lang.module.FindException: Module java.activation not found

I've tried to install the activation.jar from http://www.java2s.com/Code/Jar/a/Downloadactivationjar.htm and moved it to /usr/share/java directory (ubuntu). That is atleast what i thought i should do . Still facing this issue , please help

Download activation.jar : activation « a « Jar File Download

Download activation.jar : activation « a « Jar File Download

Hi , can anyone help ?

Since you're manually adding the activation JAR, make sure it’s added to the Java classpath or module path properly.

#

Download activation JAR: If you haven't already, you can download it from:

#

Set CLASSPATH or MODULEPATH: Move the JAR to a known location and add it to your classpath:

#

export CLASSPATH=/path/to/activation.jar:$CLASSPATH

#

Alternatively, if you're using the module path (Java 9 and above):

#

java --module-path /path/to/activation.jar --add-modules java.activation

#

After ensuring the JAR is in your classpath or module path, try running the Hadoop command again:

#

hadoop fs -mkdir /user

#

If the issue persists, you may need to adjust your Java installation or the way you're managing JARs. Let me know how it goes, and I can guide you through further steps if needed.
