Changes
-------
Updates include:
- New import source added: _DirectorySource_.
Bugs: ATLAS-2460
https://issues.apache.org/jira/browse/ATLAS-2460
Repository: atlas
Description
-------
**Background**
This implementation deals with the 'import into' part of the data migration
process.
It assumes:
- Export from older cluster is done.
- Generated file has been moved to newer cluster.
**Implementation**
During _Atlas_ server startup, the configuration parameter is checked, if that
parameter exists, all services except _DataMigrationService_ is started.
Migration is started. Atlas server is available in _MIGRATION_ mode. It
processes REST calls made only to the _AdminResource_.
Here's are the udpates:
- New configuration parameter has been added:
_atlas.migration.mode.filename=<name of the file to be imported>_
This configuration parameter is set by Ambari as part of its migration
orchestration.
- _DataMigrationService_: New service that performs async migration as soon as
Atlas server starts up.
- _ImportProgressTracker_: Added to be able to query progress of import.
- _ImportService_: Modified to send updates to _ImportProgressTracker_.
- _AdminResource.getStatus()_ Now supplies additional status about migration.
- _ServiceState_ Modified to carry additional status _MIGRATION_. This status
is set by looking at the configuration parameter above.
- _AtlasEntityStoreV1_ modified to block sending out notifications during
migration.
- _Services_ modified for special handling of _DataMigrationService_.
**CURL**
Check status using:
```
curl -X GET -u admin:admin -H "Content-Type: application/json" -H
"Cache-Control: no-cache" http://localhost:21000/api/atlas/admin/status
```

Testing (updated)
-------
**Unit tests**
Unit tests for _DirectorySource_ added.
**Functional tests**
Steps to test:
- Place the exported file say _export-1.zip_ at _/root_
- Add to _Atlas_ Ambari's customer property:
_atlas.migration.mode.filename=/root/export-1.zip_
- Ambari will prompt for a restart. Restart Atlas.
- On the server view the progress in the logs using: _tail -f
/var/log/atlas/application.log_
- Use the CURL call mentioned above and view the status and the progress of the
import.
Thanks,
Ashutosh Mestry
