Shalin Shekhar Mangar commented on SOLR-5473:
---------------------------------------------
Two comments specific to the SOLR-5474 part which has been included in the
latest patch:
# The ExpireOnGetHashMap is not thread-safe. The eviction logic in
ExpireOnGetHashMap synchronises on ‘this’ but that is insufficient. The
requestWithRetryOnStaleState method calls put and remove without synchronizing
on the map so it is open to a ConcurrentModificationException. I think we can
just extend ConcurrentHashMap instead and not worry about synchronisation at
all.
# Now that we have eliminated LazyCloudSolrServer, the method signature changes
from private to protected are no longer necessary.
> Make one state.json per collection
