massakam opened a new issue #12895: URL: https://github.com/apache/pulsar/issues/12895
**Describe the bug** When I start a standalone server built from [the current master code](https://github.com/apache/pulsar/tree/d74af88a6aed5a7da3139a4228ae29f793ec72b2), I get a lot of the following exceptions: ``` Nov 17, 2021 1:03:46 PM com.github.benmanes.caffeine.cache.LocalAsyncCache lambda$handleCompletion$7 WARNING: Exception thrown during asynchronous load java.util.concurrent.CompletionException: org.apache.pulsar.metadata.api.MetadataStoreException$ContentDeserializationException: Failed to deserialize payload for key '/counters/producer-name' at java.util.concurrent.CompletableFuture.encodeRelay(CompletableFuture.java:326) at java.util.concurrent.CompletableFuture.completeRelay(CompletableFuture.java:338) at java.util.concurrent.CompletableFuture.uniRelay(CompletableFuture.java:925) at java.util.concurrent.CompletableFuture.uniCompose(CompletableFuture.java:967) at java.util.concurrent.CompletableFuture$UniCompose.tryFire(CompletableFuture.java:940) at java.util.concurrent.CompletableFuture.postComplete(CompletableFuture.java:488) at java.util.concurrent.CompletableFuture.complete(CompletableFuture.java:1975) at org.apache.pulsar.metadata.impl.ZKMetadataStore.lambda$null$7(ZKMetadataStore.java:139) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) at java.lang.Thread.run(Thread.java:748) Caused by: org.apache.pulsar.metadata.api.MetadataStoreException$ContentDeserializationException: Failed to deserialize payload for key '/counters/producer-name' at org.apache.pulsar.metadata.cache.impl.MetadataCacheImpl.lambda$readValueFromStore$0(MetadataCacheImpl.java:111) at java.util.concurrent.CompletableFuture.uniCompose(CompletableFuture.java:966) ... 8 more Caused by: com.fasterxml.jackson.databind.exc.MismatchedInputException: No content to map due to end-of-input at [Source: (byte[])""; line: 1, column: 0] at com.fasterxml.jackson.databind.exc.MismatchedInputException.from(MismatchedInputException.java:59) at com.fasterxml.jackson.databind.ObjectMapper._initForReading(ObjectMapper.java:4688) at com.fasterxml.jackson.databind.ObjectMapper._readMapAndClose(ObjectMapper.java:4586) at com.fasterxml.jackson.databind.ObjectMapper.readValue(ObjectMapper.java:3643) at org.apache.pulsar.metadata.cache.impl.JSONMetadataSerdeSimpleType.deserialize(JSONMetadataSerdeSimpleType.java:42) at org.apache.pulsar.metadata.cache.impl.MetadataCacheImpl.lambda$readValueFromStore$0(MetadataCacheImpl.java:107) ... 9 more ``` I don't know why, but when I revert https://github.com/apache/pulsar/pull/12788, these exceptions disappear. **To Reproduce** Steps to reproduce the behavior: ```sh $ git clone [email protected]:apache/pulsar.git $ cd pulsar $ mvn clean install -DskipTests=true $ ./bin/pulsar standalone -nfw -nss --wipe-data ``` **Desktop (please complete the following information):** - OS: CentOS 7 -- This is an automated message from the Apache Git Service.
