ql/src/java/org/apache/hadoop/hive/ql/optimizer/physical/SparkMapJoinResolver.java <https://reviews.apache.org/r/27627/#comment101882> This assumes that result SparkWorks will be linearly dependent on each other, which isn't true in general.Let's say the are two works (w1 and w2), each having a map join operator. w1 and w2 are connected to w3 via HTS. w3 also contains map join operator. Dependency in this scenario will be graphic rather than linear. - Xuefu Zhang On Nov. 7, 2014, 6:07 p.m., Chao Sun wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
