Jay Zhuang commented on CASSANDRA-13060:
----------------------------------------
The root cause is fixed by CASSANDRA-12281. Patched "[Avoid blocking gossip
during pending range
calculation|https://github.com/spodkowinski/cassandra/commit/2611e33720233ad724b2196f5c062ef5c58ecd10]";
to 3.0.10 and confirmed no NPE. Thanks [[email protected]] for the fix.
On the other hand, it's still worth doing null check in
[StorageService|https://github.com/cooldoger/cassandra/commit/3f85e4ffb531c82ee16b8f6cf9b4c4e29ae1fd53]
as a small improvement.
