------------------------------------
Summary: Beeline: Isolating dependencies and execution with java
Key: HIVE-24348
URL: https://issues.apache.org/jira/browse/HIVE-24348
Project: Hive
Issue Type: Improvement
Components: Beeline
Affects Versions: 3.1.0
Reporter: Naveen Gangam
Assignee: Naveen Gangam
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
