Step2:Configuring Hadoop’s Java Home is not clear

[buddhikac96]

Hi @anjalysam. Thank you so much for the document. Still, it's not clear to me how to configure Hadoop's JAVA_HOME in Colab. I don't know what to do in the following step.

To set java path, go to /usr/local/hadoop-3.3.0/etc/hadoop/hadoop-env.sh then
. . . export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/ . . .

I truly appreciate if you could update the document on how to do the above task in Google Colab.

Thank you.

Hi!
I added the code below and problem solved.
import os
os.environ["JAVA_HOME"] = "/usr/lib/jvm/java-8-openjdk-amd64"

Hi,
Open the hadoop-env.sh (location: hadoop-3.3.0/etc/hadoop/hadoop-env.sh) and find the line start with export JAVA_HOME. Replace that line with export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/

I tried your way but it didn't work. However, when I tried with the way @MohammadZp proposed, it worked. I just don't understand why
