Zhihua Deng commented on HIVE-25188:
------------------------------------
Hey [~belugabehr], As you have seen it, if user creates such tables to
retrieve the "data" field, exception will be thrown, though the input is a
valid complete json, so here I propose to answer the struct value to the "data"
field, like that we can get the value mapping to the field "data" using the
json lib.
Thanks, Zhihua Deng
