Hemanth Yamijala created ATLAS-628:
--------------------------------------
Summary: Starting two Atlas instances at the same time causes
exceptions in HA mode.
Key: ATLAS-628
URL: https://issues.apache.org/jira/browse/ATLAS-628
Project: Atlas
Issue Type: Bug
Reporter: Hemanth Yamijala
Priority: Blocker
Configure HA parameters for Atlas. Use SOLR and HBase as backends. From two
terminals start two instances of Atlas at roughly the same time. This causes
failure exceptions and at least one instance does not start up properly (in
either active or passive mode). The relevant stack trace is:
