Review request for hive. Summary ------- Suppose the table schema is (a string, b string) partitioned by (p1 string, p2 string), a dynamic partition insert is allowed to: insert overwrite ... partition (p2="...", p1); which will create the wrong HDFS directory structure such as /.../p2=.../p1=.... This is contradictory to the metastore's assumption of the HDFS directory structure. This addresses bug HIVE-2519. https://issues.apache.org/jira/browse/HIVE-2519 Diffs ----- trunk/ql/src/java/org/apache/hadoop/hive/ql/parse/BaseSemanticAnalyzer.java 1188024 trunk/ql/src/java/org/apache/hadoop/hive/ql/parse/ErrorMsg.java 1188024 trunk/ql/src/test/queries/clientnegative/dyn_part4.q PRE-CREATION trunk/ql/src/test/results/clientnegative/dyn_part4.q.out PRE-CREATION Diff: https://reviews.apache.org/r/2541/diff Testing ------- ant test Thanks, Ning
