Namit Jain commented on HIVE-1707:
----------------------------------
1. I dont think we should add a new varaible "hive.exec.partition.usetable.dfs"
-
we should always use table dfs.
2. I think there is a bug when the table's location does not contain the fs (in
SemanticAnalyzer).
Path tabPath = dest_tab.getPath();
Path partPath = dest_part.getPartitionPath();
if (conf.getBoolVar(HiveConf.ConfVars.HIVEPARTITIONUSETBLDFS)) {
// if the table is in a different dfs than the partition,
// replace the partition's dfs with the table's dfs.
dest_path = new Path(tabPath.toUri().getScheme(), tabPath.toUri()
.getAuthority(), partPath.toUri().getPath());
} else {
We should pick the default fs then.
3. Path newPartPath = new Path(loadPath.toUri().getScheme(), loadPath
.toUri().getAuthority(), oldPartPath.toUri().getPath());
same as above in Hive.java
4. if (partPath != null
&& !partPath.equalsIgnoreCase(tpart.getSd().getLocation())) {
tpart.getSd().setLocation(partPath);
}
Cant we always set the location ?

> Project: Hadoop Hive
> Issue Type: Bug
> Components: Query Processor
> Reporter: Namit Jain

> Fix For: 0.7.0

> Attachments: hive-1707.1.patch

>
> The following does not work:
> create table T -> default location dfs1
> insert overwrite T partition (ds='1') select * from src;
> alter table T location 'dfs2';
> insert overwrite T partition (ds='1') select * from src;
> It tries to insert back in dfs1 - due to which the move task fails.
> It would be cleaner to keep the same semantics as fileformat - whenever a
> partition is being inserted into, it
> inherits the properties from the table. So, after the insert, the partition
> should belong to dfs1.
> It does not matter whether the partition exists before or not,.
