-----------------------------------
Summary: Atlas says it is successfully started even if the index
engine is not working.
Key: ATLAS-2315
URL: https://issues.apache.org/jira/browse/ATLAS-2315
Project: Atlas
Issue Type: Bug
Environment: Mac dev master
Reporter: David Radley
Atlas says it is successfully started even if the index engine is not working.
Atlas does not check that that the index engine is working before saying that
Atlas has successfully started.
One way to handle this would be to have stages of initialization, including:
- If embedded Hbase
- embedded backing store started
- embedded backing store accepting requests
- If embedded index
- embedded index started
- embedded index accepting requests
if not embedded index
- index engine verified to be active.
- servlet engine started
- servlet engine accepting Rest calls
Another approach would be to check that JanusGraph is sane prior to starting
Atlas and separating out any starting of embedded and verification of Janus
from any Atlas specific code.
There needs to appropriate message so there is an obvious action to be taken
when the dependent components are not there when starting atlas using
atlas_start.py.
I am currently seeing issues when I have an Atlas built and running with
embedded Solr and Hbase and Janus. I then re build - the index / Hbase are not
cleaned up - so I get errors when attempting to start atlas again, all the
best, David.
