Installing Hadoop

OpenTSDB requires Hadoop to function correctly. Therefore, you need to install Hadoop first before installing OpenTSDB.

1. Download Hadoop and extract it:

tar xzf hadoop-3.3.0.tar.gz
mv hadoop-3.3.0 /usr/local/hadoop

2. Set the required environment variables:

export JAVA_HOME=/usr/lib/jvm/java
export HADOOP_HOME=/usr/local/hadoop
export PATH=$PATH:$HADOOP_HOME/bin

3. Verify Hadoop:

hadoop version

If everything goes well, it should show the version of Hadoop.
