Hello, I just found two different instances of blazegraph set up with .war files are using the same bigdata.jnl file due to the default setting using the root folder of server container instead of the root of the instance folder. I wonder if there is any potential problem with different instances using the same jnl file? And are there ways to seperate the data for the two instances now? Thanks!

Thanks! Are the data saved properly in the file from the two instances? In term of not safe it is about one instance can access the data from the other? Is there way to separate them now?
And is there way to view the jnl file like viewing database in a mysql or postgresql client gui? Thanks.

Thanks! I am a bit confused re different processes and instances above. War files set up folders under server container, they are different processes (I called them instances in the questions)? And we can have multiple name space stores under the process running under the folder?
It would be good to add in the setup guide the need to change the default data location and which setting files to change (eg. need to change both GraphStore.properties and RWStore.properties), user won't know it needs to be changed and how... Thanks.
