> When creating a table, Hive uses URI to represent location:
> {code}
>     if (crtTbl.getLocation() != null) {
>       tbl.setDataLocation(new Path(crtTbl.getLocation()).toUri());
>     }
> {code}
> When adding a partition, Hive uses Path to represent location:
> {code}
>       // set partition path relative to table
>       db.createPartition(tbl, addPartitionDesc.getPartSpec(), new Path(tbl
>                     .getPath(), addPartitionDesc.getLocation()), addPartitionDesc.getPartParams(),
>                     addPartitionDesc.getInputFormat(),
>                     addPartitionDesc.getOutputFormat(),
>                     addPartitionDesc.getNumBuckets(),
>                     addPartitionDesc.getCols(),
>                     addPartitionDesc.getSerializationLib(),
>                     addPartitionDesc.getSerdeParams(),
>                     addPartitionDesc.getBucketCols(),
>                     addPartitionDesc.getSortCols());
> {code}
> This disparity makes the values stored in metastore be encoded differently, causing problems
w.r.t. special character as demonstrated in HIVE-5446. As a result, the code dealing with
location for table is different for partition, creating maintenance burden.
> We need to standardize it to Path to be in line with other Path related cleanup effort.
