--------------------------------------
Summary: st_intersects incorrect with multlinestring
Key: HIVE-29726
URL: https://issues.apache.org/jira/browse/HIVE-29726
Project: Hive
Issue Type: Bug
Reporter: Csaba Ringhofer
select st_intersects(st_geomfromtext('LINESTRING(0 0, 9 0, 0 9)'),
st_geomfromtext('MULTILINESTRING((1 10, 2 10), (10 10, 10 1))'));
The query above returns true in Hive, while it should return false.
Cross checked with postgis, which returns false.
Discover this when testing Apache Impala's new c++ implementation that used
boost::geometry, which also returns false.
