Hoss Man commented on SOLR-2608:
--------------------------------
I can't comment on the specific exceptions mentioned above, but havin recently
looked at TestReplicationHandler because of SOLR-3809 i noticed a few things i
thought i'd comment on here...
at some point it was annotated as @Slow - i believe the crux of the problem
with why it can be very slow for some people is that the majority of the
functionality being tested seems to rely on the slave polling the master for
replication, and the "rQuery" method used through out the test will retry
queries over and over (up to 30 seconds) until they pass.
While we should definitley have some test that the polling works, a lot of the
functionality not-polling specific could probably be tested more reliably using
"on demand" snappulling commands to the slave.
