--------------------------------------
Summary: Data Migration: Export: Type Definition Fails to Export
in HA Mode
Key: ATLAS-2652
URL: https://issues.apache.org/jira/browse/ATLAS-2652
Project: Atlas
Issue Type: Bug
Components: atlas-core
Affects Versions: 0.8.2
Reporter: Ashutosh Mestry
Assignee: Ashutosh Mestry
Fix For: 0.8.2
*Pre-requisites*
Setup a multi-node cluster such that high availability (HA) mode is enabled.
This will mean that Atlas server is present on more than 1 node.
In _atlas-application.properties_, note that the _atlas.server.ha.enabled_ is
set to _true_.
Add some data to Atlas repository, either via Import or by creating tables
within Hive.
*Steps to Reproduce*
* Stop Atlas via Ambari.
* Start the migration using _atlas_migration_export.py -d ~/atlas-data_
Expected results: Both the JSON files generated should contain data.
Actual results: _atlas-migration-typesdef.json_ does not contain data.
The _atlas-migration-exporter.log_ shows a message
_'AtlasTypeDefStoreInitializer.init(): deferring type loading until instance
activation'_.
*Root Cause*
In HA mode, the Atlas type system is initialized only when the active node.
