In pom.xml of hbase-spark, jruby-complete is excluded from some of HBase child modules, there are 2 issues:
1. jruby-complete is excluded from the following child modules,
but those child modules does not introduce jruby-complete. jruby-complete is only introduced by hbase-shell, and by transitive dependency, it is also introduced by hbase-assembly, as hbase-assembly depends on hbase-shell.
But none of 3 modules listed above introduces jruby-complete.
2. The exclusion of jruby-complete is stated twice in each of the 3 child modules listed in 1.
