------------------------------
Attachment: HIVE-6185.patch
> DDLTask is inconsistent in creating a table and adding a partition when
> dealing with location
> ---------------------------------------------------------------------------------------------
>
> Key: HIVE-6185
> URL: https://issues.apache.org/jira/browse/HIVE-6185
> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Affects Versions: 0.12.0
> Reporter: Xuefu Zhang
> Assignee: Xuefu Zhang
> Attachments: HIVE-6185.patch
>
>
> 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.
