<https://reviews.apache.org/r/1105/#comment2131>

    Do we really need a new metastore function? Can we just use 
alter_partition()?



trunk/metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java
<https://reviews.apache.org/r/1105/#comment2126>

    This doesn't seem to be correct to me. The partition should always have 
SerDe. Even if it doesn't have one, copying from the table's Serde doesn't seem 
to be the right thing to do.



trunk/metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java
<https://reviews.apache.org/r/1105/#comment2127>

    Also, it doesn't seem to be correct to me here. There shouldn't be any case 
that we need to create new directory for the renamed partitions. Renaming 
should just change the name, with all other attributes kept.



trunk/metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java
<https://reviews.apache.org/r/1105/#comment2128>

    I can't understand those codes. What you try to do here?



trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/DDLTask.java
<https://reviews.apache.org/r/1105/#comment2129>

    Since we only need old part spec and new part spec, why we make a new 
Partition object at all?



trunk/ql/src/java/org/apache/hadoop/hive/ql/parse/DDLSemanticAnalyzer.java
<https://reviews.apache.org/r/1105/#comment2130>

    why we still continue when tab is null?



trunk/ql/src/java/org/apache/hadoop/hive/ql/plan/HiveOperation.java
<https://reviews.apache.org/r/1105/#comment2125>

    Privilege.ALTER_METADATA doesn't sound right to me here. Can you use 
Privilede.DROP and Priviledge.CREATE?



trunk/ql/src/java/org/apache/hadoop/hive/ql/plan/RenamePartitionDesc.java
<https://reviews.apache.org/r/1105/#comment2124>

    Looks like you copied from the file AddPartitionDesc, but do you need all 
those class members for renaming partition?

bq.  Review request for Siying Dong.

bq.  
bq.  Summary
bq.  -------
bq.  
bq.  Implement ALTER TABLE PARTITION RENAME function to rename a partition. 
bq.  Add HiveQL syntax "ALTER TABLE bar PARTITION (k1='v1', k2='v2') RENAME TO 
PARTITION (k1='v3', k2='v4');"
bq.  This is my first Hive diff, I just learn everything from existing codebase 
and may not have a good understanding on it. 
bq.  Feel free to inform me if I make something wrong. Thanks

bq.  -------
bq.  
bq.  Add a partition A in the table
bq.  Rename partition A to partition B
bq.  Show the partitions in the table, it returns partition B.
bq.  SELECT the data from partition A, it returns no results
bq.  SELECT the data from partition B, it returns the data originally stored in 
partition A
