Ananth commented on APEXMALHAR-2542:
------------------------------------
The root cause is that the application is expecting a file in the path
/tmp/circleMapping.txt as the exception suggests. This path is being configured
in the application properties file.
There are a couple of options to fix this.
# Let the build system copy the file into the target location as a pre-build
step. - Not a great solution as the test will fail on local systems
# Copy the file in the resources folder as bundled in the jar to the actual
location that is configured in the properties file of the application. This
will work for almost all of the systems. The issue however is that this cannot
be a solution for a true cluster based test. ( as the copy is happening in the
driver/application code as opposed to the operator ). Also the path
"/tmp/circleMapping.txt" implies a Unix styled OS and hence this approach will
not work when being built on windows. (assuming no Cygwin styled build)
Option 2 is being implemented as a fix to the problem.
