Re: Throw ExecutionException for E() syntax
hadoopmarc@...
No, the query syntax is not correct.
See https://javadoc.io/doc/org.apache.tinkerpop/gremlin-core/latest/index-all.html#I:V
and you not that V() exists for both the GraphTraversalSource, the GraphTraversal and for __.
Look again at https://javadoc.io/doc/org.apache.tinkerpop/gremlin-core/latest/index-all.html#I:E
and you see that E() only exists for the GraphTraversalSource.
In other words: a mid-traversal E() is not allowed and you get the error that more or less says so.
Best wishes, Marc
