/var/log/hadoop/hdfs/hadoop-hdfs-datanode-worker2.sip.com.out.2 
Error: could not find libjava.so Error: Could not find Java SE Runtime Environment


We see the above error in your DataNode startup logs. Please validate the same with the user who is running the DataNOde process using the command:

# java -version

# su - hdfs
# java -version


this error indicates that you Might not have a Valid JDK installed on your machine.


So please try this:

1. Install a Valid JDK 1.8 on your machine. You can download one from here: https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html


2. set the JAVA_HOME as following inside the "/etc/profile" or inside the "~/.bash_profile" file"

export JAVA_HOME=/PATH/TO/jdk1.8.0-120
export PATH=$JAVA_HOME/bin:$PATH


The path "/PATH/TO/jdk1.8.0-120" is a dummy path please use your own JDK path here.
