INLINE COMMENTS
ql/src/test/queries/clientpositive/truncate_table.q:3 Isn't readnputs and
writeInputs populated correctly for truncate ?
If yes, shouldn't these commands fail for src/srcpart etc.
ql/src/java/org/apache/hadoop/hive/ql/parse/DDLSemanticAnalyzer.java:748 I
remember you added a new function getTable() to do all error checking etc.
Cant you re-use that ?
ql/src/test/queries/clientpositive/truncate_table.q:8 What is the behavior
for a non-partitioned table, when partition spec. is not specified ?
Either throw an error, or truncate all partitions ?
Support specifying partial partition specifications:
truncate table srcpart partition (ds='2008-04-08' hr);
ql/src/java/org/apache/hadoop/hive/ql/parse/DDLSemanticAnalyzer.java:759 It
should be possible to specify partial partn specifications
ql/src/java/org/apache/hadoop/hive/ql/parse/DDLSemanticAnalyzer.java:754 add
negative test for this.
ql/src/java/org/apache/hadoop/hive/ql/exec/DDLTask.java:3895 inputs/outputs
not populated
