During HBASE-15128, i made some changes to ruby script, it cause a lot of warning about ruby style.
https://builds.apache.org/job/PreCommit-HBASE-Build/587/artifact/patchprocess/diff-patch-rubocop.txt A lot of warnings exist already, i think it is unreasonable. for example: 1. /testptch/hbase/hbase-shell/src/main/ruby/hbase/admin.rb:32:3: C: Class has too many lines. [777/100] The class length has exceeded 100 already. 2. /testptch/hbase/hbase-shell/src/main/ruby/hbase/admin.rb:135:81: C: Line is too long. [99/80] I think length 100 is more reasonable. 3. /testptch/hbase/hbase-shell/src/main/ruby/hbase/admin.rb:145:30: C: Prefer single-quoted strings when you don't need string interpolation or special symbols. I see many strings in script use double-quoted. wdyt?
