[jira] [Updated] (ATLAS-129) Atlas cannot use Cassandra as the
storage backend.
[ https://issues.apache.org/jira/browse/ATLAS-129?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
liutongfeng updated ATLAS-129:
------------------------------
Description:
When using Atlas out of Hadoop cluster, I use Cassandra as the storage backend, but got the following errors, and did not work. Does Atlas support Cassandra now?
