currently hive/lib has both
- hive-jdbc.jar
- hive-jdbc-standalone.jar
We should probably remove hive-jdbc-standalone.jar from hive/lib because it
contains slf4j classes.
Hadoop lib has slf4j classes already and it will be warning message if
there is slf4j class duplicates in classpath
hive-jdbc-standalone.jar is used by
- beeline (bin/ext/beeline.sh:27 jdbcStandaloneJarPath=`ls
${HIVE_LIB}/hive-jdbc-*-
standalone.jar`
)
- jdbc clients (e.g. SQuirreL SQL, SQL Workbench/J, etc)
So, where should we put hive-jdbc-standalone.jar if we move it from
hive/lib?
Several options:
- hive root
- hive/ext (new folder)
- hive/share (new folder)
