DSE Graph
Troubleshooting
Troubleshooting
How to troubleshoot common issues with DSE Graph.
drop() hangs
drop() hangs in the Gremlin console.
Gremlin console hangs or behaves erratically
Tips to use when the Gremlin console hangs or behaves erratically.
Queries sporadically fail with LOCAL_ONE/LOCAL_QUORUM
Queries in multi-datacenter clusters sporadically fail with a replication factor set to LOCAL_ONE or LOCAL_QUORUM.
Consistency level and graph.addVertex()
A consistency level of ONE can cause inconsistent behavior during vertex creation.
Issues creating a graph cluster using Lifecycle Manager (LCM)
LCM incorrectly configures some necessary information for DSE Graph.
Shutting down Studio Gremlin process
Studio can have its state hung because a command in a cell that will not terminate.
Dropping edge property drops edges
For existing graph data created prior to DSE 5.0.5, dropping an edge property can drop the edge.
Creating graph with options while unified authentication is enabled fails
Creating a graph with options while unified authentication is enabled will fail.
Do not upgrade to DSE 5.0.6 if using PVTs
Upgrading to DSE 5.0.6 if using PVTs may cause failure.
