Zach York commented on HBASE-18775:
-----------------------------------
[~tedyu] Can you clarify which File you are talking about for:
bq. + private static final TableName TABLE_NAME =
TableName.valueOf("TestGlobalReadOnly");
I changed TestGlobalReadOnly to try to create a non-default namespace. Perhaps
if you have more comments on this, it would be better to do it in RB.
bq. + config.setBoolean("hbase.testing.nonamespacemanager", true);
bq. Why is the above needed ?
This is actually unnecessary now. In branch-1 there was a NamespaceManager that
would fail to initialize if the default and system namespaces weren't created
and couldn't be created. This is not an issue anymore. I have updated the patch
to reflect this.
> Add a Global Read-Only property to turn off all writes for the cluster
