Hello,
What are some common or good ways to handle indexing
If you're using the delta import handler the problem would seem to go
away because you can have two separate masters running at all times,
and if one fails, you can then point the slaves to the secondary
master, that is guaranteed to be in sync because it's been importing
from the same database?

Yes, I think this should be pushed upstream - insert a tee in the
document stream so that all documents go to both masters.
Then use a load balancer to make requests

If you have a wrapper, like an indexer app which prepares solr docs and
sends them
Oh, there is no DB involved. Think of a document stream continuously coming
in,
a component listening to that stream, grabbing docs, and pushing it to
master(s).
I don't think Solr is designed for this use case, eg, I wouldn't
expect deterministic results with the current architecture as
specialty.

How about with DRBD? I know people use DRBD to keep 2 Hadoop NNs (their edit

I guess you could put a LB between slaves and masters, never thought of

What are some common or good ways to handle indexing (master) fail-over?
Imagine you have a continuous stream of incoming documents that you have to

How do you set up you masters?
