Gremlin console hangs or behaves erratically 

Tips to use when the Gremlin console hangs or behaves erratically.

The DataStax Enterprise Help Center also provides troubleshooting information.

The Gremlin console can quit responding if a bad query is entered. Here are some hints for how to regain control:
:clear
This command will clear the current buffer and reset the prompt counter.
:remote config alias reset
This command will reset the graph traversal g to no graph. Use this command before running system commands.
:remote config alias g some_graph.g
This command will reset the graph traversal g to another graph. If queries are hanging in the current graph, switching to another graph allows the console to respond.
