The job was developed in single node. Both the environments are running with single node, the job runs fine in the old environment and it doesn't run with the new environment.
Here is the strange part, the same job run fine in the new environment with the multi-node[with 2 node] ..
with the more search, I found out in V8.0.1 the similar issue and resolution
Code: Select all
If running in a single-node configuration, a job might hang or fail to run with the error "A cycle was found in the combined graph. Failed describing Operator Combinations."
Workaround
Set the APT_NO_ONE_NODE_COMBINING_OPTIMIZATION environment variable. (eCase 116847)
I am wondering is there anything for 7.5.1A .. anyone know about this?
