Does pig ever share same instance of object concurrently at run time? Or
does it create a new instance for every invocation? I wrote UDF with a
public data member (not static) but I wonder if that is thread safe.

New object per occurrence in script per mapper (or reducer).

Pig is not multi-threaded, so concurrency shouldn't be an issue.
