No, it isn't normal. The implication so far is that this was not noticed by the crew before getting airborne and therefore was a major factor in the accident. At what stage the starboard spoiler became extended and then didn't retract is another question. Hard to believe it would have been extended during a (if any) pre-flight walkaround.
