Chris Nauroth commented on HDFS-9062:
-------------------------------------
Thanks for the additional details, James. I hadn't made the connection that
you were looking to do an external setup, with the mini-cluster in a separate
process from the test executable.
If I understand correctly then, the proposal is to add a new argument to
{{MiniDFSClusterManager}}, which if present triggers a call to
{{DomainSocket#disableBindPathValidation}}. Is that right? If so, then it
sounds like a reasonable change.
> Add a parameter to MiniDFSCluster to turn off security checks on the domain
> socked path

> I'd like to add a command line parameter that allows the permission checks on
> dfs.domain.socket.path to be turned off.
> Right now a blocker, or at least major inconvenience, for short circuit
> reader development is getting the domain socket path set up with the correct
> permissions. I'm working on shared test machines where messing with things
> in /var/lib is discouraged.
> This should also make it easier to write tests for short circuit reads once
> completed.
