Hi all,
I have been working on this problem for a week now, finally found a fix to it! Problem: I can install my services fine, but when trying to start history server/ node manager, it will return error as "Error: Could not find or load main class org.apache.hadoop.fs.FsShell" This is due to environment not set up correctly since on my cluster, I had HADOOP_PREFIX and HADOOP_CONF_DIR pointing to my none HDP hadoop. Fix: edit this file: /usr/lib/hadoop/libexec/hadoop-config.sh just add unset HADOOP_PREFIX unset HADOOP_CONF_DIR somewhere before it calls hadoop-layout.sh unset your other hadoop variables as well if you set them up earlier. Good luck to all! Yixiao Lin
