  2. Paths have changed in HDP 2.3. Make sure you remove old path specifications from hadoop-env.sh, such as:

    export JAVA_LIBRARY_PATH=/usr/lib/hadoop/lib/native/Linux-amd64-64

    If you leave these paths in your hadoop-env.sh file, the lzo compression code do not load, as this is not where lzo is installed.
