Change subject: MPALA-10482: Select-star query on unrelative collection column of transactional table hits IllegalStateException ...................................................................... MPALA-10482: Select-star query on unrelative collection column of transactional table hits IllegalStateException SELECT * query on unrelative collection column of transactional ORC table will hit IllegalStateException. The AcidRewriter will rewrite queries like "select item from my_complex_orc.int_array" to "select item from my_complex_orc t, t.int_array" This cause troubles in star expansion. Because the original query "select * from my_complex_orc.int_array" is analyzed as "select item from my_complex_orc.int_array" But the rewritten query "select * from my_complex_orc t, t.int_array" is analyzed as "select id, item from my_complex_orc t, t.int_array". The workaround is to keep track of the automatically added table refs during query rewrite. So when we analyze the rewritten query we can ignore these auxiliary table refs when doing star expansion.
