#execute SET with leading spaces faulty in Hive 2 with :hive_version 12

There appears to be an issue with using SET commands where there are leading spaces in the query. This affects Hive 2 #tcli_connect with options { :hive_version => 12 }. In Hive 1 with #connect, however, this appears to work as expected. Compare the working:

RBHive.tcli_connect('hive.example.com', 10002, { :hive_version => 12 }) do |conn|
  conn.execute("SET mapred.fairscheduler.pool=swimming")
  conn.execute("SELECT * FROM chairs")
end

which results in mapred.fairscheduler.pool being set to swimming, with the seemingly faulty:

RBHive.tcli_connect('hive.example.com', 10002, { :hive_version => 12 }) do |conn|
  conn.execute("    SET mapred.fairscheduler.pool=swimming")
  conn.execute("SELECT * FROM chairs")
end

RBHive.tcli_connect('hive.example.com', 10002, { :hive_version => 12 }) do |conn|
  conn.execute(%Q{
    SET mapred.fairscheduler.pool=swimming
  })
  conn.execute("SELECT * FROM chairs")
end

which results in SET mapred.fairscheduler.pool being set to swimming and the setting not being applied (note the leading SET).

Since there has been no reply to this in over 6 years, I'll go ahead and close it.
