Hi,
Configuration should synchronize in Spark cluster setup.
Your issue may be related to SIC failure between the members.
In order to verify SIC is valid you can test file copying between the members over SIC channel. This is an example of a command you can initiate from the primary member, assuming you are using default Sync settings:
cprid_util getfile -local_file /logs/test_pt -remote_file /pfrm2.0/bin/pt -server 10.231.149.2
If /logs/test_pt is successfully created then SIC and communication between the members is functioning well. If not then please issue support ticket and include return value of this command.
Thanks.
