> Currently, beeline code, binaries and executables are somewhat tightly coupled with the hive product. To be able to execute beeline from a node with just JRE installed and some jars in classpath is impossible.
> * beeline.sh/hive scripts rely on HADOOP_HOME to be set which are designed to use "hadoop" executable to run beeline.
> * Ideally, just the hive-beeline.jar and hive-jdbc-standalone jars should be enough but sadly they arent. The latter jar adds more problems than it solves because all the classfiles are shaded some dependencies cannot be resolved.
> * Beeline has many other dependencies like hive-exec, hive-common. hadoop-common, supercsv, jline, commons-cli, commons-io, commons-logging etc. While it may not be possible to eliminate some of these, we should atleast have a self-contains jar that contains all these to be able to make it work.
> * the underlying script used to run beeline should use JAVA as an alternate means to execute if HADOOP_HOME is not set
