I ran the 1270-1194 patch continually overnight (trunk) in my ci env, after ~25 test runs I saw 4 failures:
1) #402 - QuorumTest.testFollowersStartAfterLeader 2) #407 - org.apache.zookeeper.test.FLETest.testLE 3) #410 - org.apache.zookeeper.test.AsyncHammerTest.testHammer 4) #415 - org.apache.zookeeper.test.AsyncHammerTest.testHammer 1) client could not connect to reestablished quorum: giving up after 30+ seconds. 2) known flakey test 3) QP failed to shutdown in 30 seconds: QuorumPeer[myid=3]0.0.0.0/0.0.0.0:11224 4) QP failed to shutdown in 30 seconds: QuorumPeer[myid=1]0.0.0.0/0.0.0.0:11222 On the plus side no "testearlyleaderabandon" failures. On the minus side 3/4 are a bit worrysome. Searching back through all my previous failures I don't see this happening. Perhaps these changes have shifted some timing? My main concern is that this might be caused directly by the patch itself.... Patrick
