Sean Busbey commented on HBASE-21027:
-------------------------------------
the test failures are because of the collector:
{code}
68 // No synchronization here because weakly consistent view should be
good enough
69 return registeredDeserializers.entrySet().stream()
70 .collect(Collectors.toMap(Map.Entry::getKey, v ->
v.getClass().getName()));
{code}
the value mapper function takes a Map.Entry as a value, so we store the fqcn
for Map.Entry over and over. should be {{entry ->
entry.getValue().getClass().getName()}} I think?
> Inconsistent synchronization in CacheableDeserializerIdManager
