Description
While working on SOLR-9014 I came across a strange test failure.
[junit4] ERROR 16.9s | AsyncCallRequestStatusResponseTest.testAsyncCallStatusResponse <<< [junit4] > Throwable #1: com.carrotsearch.randomizedtesting.UncaughtExceptionError: Captured an uncaught exception in thread: Thread[id=46, name=OverseerStateUpdate-95769832112259076-127.0.0.1:51135_z_oeg%2Ft-n_0000000000, state=RUNNABLE, group=Overseer state updater.] [junit4] > at __randomizedtesting.SeedInfo.seed([91F68DA7E10807C3:CBF7E84BCF328A1A]:0) [junit4] > Caused by: java.lang.AssertionError [junit4] > at __randomizedtesting.SeedInfo.seed([91F68DA7E10807C3]:0) [junit4] > at org.apache.solr.cloud.overseer.ZkStateWriter.writePendingUpdates(ZkStateWriter.java:231) [junit4] > at org.apache.solr.cloud.Overseer$ClusterStateUpdater.run(Overseer.java:240) [junit4] > at java.lang.Thread.run(Thread.java:745)
The underlying problem can manifest by tripping the above assert or a BadVersionException as well. I found that this was introduced in SOLR-7281 where a new 'downnode' command was added.
