Shengsheng Huang commented on HIVE-3148:
----------------------------------------
I dumped the AST of the ALTER command using explain, and found it already build
the wrong node, as below.
(TOK_ALTERTABLE_ADDPARTS t (TOK_PARTSPEC (TOK_PARTVAL p 1))
(TOK_PARTITIONLOCATION '/Users/carl/1') (TOK_PARTSPEC (TOK_PARTVAL p 2))
(TOK_PARTITIONLOCATION '/Users/carl/1'))
In the above AST, TOK_PARTSPEC (specification of partition) and
TOK_PARTITIONLOCATION (partition location) nodes are all siblings, which does
not make much sense to me. So in my patch I rearranged the AST a bit by
attaching the TOK_PARTITIONLOCATION to TOK_PARTSPEC node, as below:
(TOK_ALTERTABLE_ADDPARTS t (TOK_PARTSPEC (TOK_PARTVAL p 1)
(TOK_PARTITIONLOCATION '/Users/carl/1')) (TOK_PARTSPEC (TOK_PARTVAL p 2)
(TOK_PARTITIONLOCATION '/Users/carl/2')))
This way locations can correctly identified and analyzed.
