Thanks for reporting Zhou. Can you provide your schema file and the SQL query you ran? Or if not the whole file, at least the portions that are relevant to the query?

--schema.json --(pwd:/home/hadoop/conf/schema.json)

{ "tables": [ { "name": "human", "columns": [ {"name": "name", "type": "string"}, {"name": "gender", "type": "string"} ] } ], "relationships": [] }

--execute script:

graph = TitanFactory.open('conf/hbase.properties')

g = graph.traversal()

configFn = "/home/hadoop/conf/schema.json"

:remote connect sql.gremlin graph configFn

:> select * from human
