Bugs: ATLAS-1825
    https://issues.apache.org/jira/browse/ATLAS-1825


Repository: atlas


Description
-------

Please refer to [ATLAS-1825](https://issues.apache.org/jira/browse/ATLAS-1825) 
for scenarios and solution approach.

Impact
======
* New class _AtlasImportTransform_ is now part of _AtlasImportRequest_. This 
holds a map of entity-type to attribute and the tranforms to be applied.
* New class _AtlasImportTransformBuiler_ reads the requests specified in the 
query string of the import API and creates a _AtlasImportTransfor_ structure.
* _AtlasImportTransformBuiler_ has new classes that support transformations. 
They are:
    * _replace_ Implements find and replace on attribute values.
    * _lowercase_ Converts attribute value to lower case. 
* Additional classes that unit test these classes have been added.

Implementation Approach
=======================
* _ZipSource_ now accepts _AtlasImportTransform_ object. It applies the 
transform every entity that is fetched from the source.

CURL
====
```
curl -g -X POST -u admin:admin -H "Content-Type: application/octet-stream" -H 
"Cache-Control: no-cache" --data-binary @../docs/DefaultDB-Stocks-2.zip 
"http://localhost:21000/api/atlas/admin/import?tr={'transforms':{'hive_db':{'qualifiedName':['lowercase','replace:@cl1:@cl2']}}}"
```
```
curl -g -X POST -u admin:admin -H "Content-Type: application/octet-stream" -H 
"Cache-Control: no-cache" --data-binary @../docs/DefaultDB-Stocks-2.zip 
"http://localhost:21000/api/atlas/admin/import?tr={'transforms':{'hive_table':{'qualifiedName':['replace:@cl1:@cl2']}}}"
```

Note: _-g_ needs to be added to CURL calls to prevent gobble check.

Documentation
=============
Need to update TWIKI documents.

Testing
-------

**Unit Test**
* Added tests for *AtlasImportTransformBuilder* and contained classes.
* Updated *ZipSourceTest*
* Added tests to *ImportServiceTest* to exercise new option.

**Functional Test**
* Small size data export & import.
* Medium size data export & import.

**Performance Tests**
Not exhaustive. Simple stop watch tests to compare against baseline.


Thanks,
