rdhabalia opened a new pull request #3240: timeout stuck producer/consumer operation request URL: https://github.com/apache/pulsar/pull/3240 ### Motivation Sometimes due to broker's bug, broker could not complete producer/consumer creation request and in this case, client is not timing out which causes stuck producer/consumer/replicator-producer. Recently we have seen that due to below exception replication producer gets stuck and remote broker is not notifying to the repl-producer. ``` Caused by: java.lang.NullPointerException at org.apache.pulsar.broker.service.persistent.PersistentTopic.hasSchema(PersistentTopic.java:1815) ~[pulsar-broker-2.2.2-yahoo.jar:2.2.2-yahoo] at org.apache.pulsar.broker.service.ServerCnx.lambda$25(ServerCnx.java:836) ~[pulsar-broker-2.2.2-yahoo.jar:2.2.2-yahoo] at java.util.concurrent.CompletableFuture.uniAccept(CompletableFuture.java:656) ~[?:1.8.0_131] ... 24 more ``` ### Modifications Client producer/consumer creation timesout after configured operation-timeout if broker doesn't complete request in a given timeout. ### Result It helps to unblock stuck producer/consumer request.
