2019-04-14 14:51:40 UTC - Cristian: Hello guys. I'm running a simple Flink job that writes from Kafka to Pulsar. It was working fine for months, until the job started failing with:
```

2019-04-14 14:52:53 UTC - Cristian: Neither the job nor the Pulsar cluster had any changes, so I can't explain why it would start failing all of a sudden. Also, if I ssh into the machine running the job, I'm able to connect to the Pulsar cluster just fine.
----
2019-04-14 14:55:25 UTC - Cristian: I'm running the Pulsar Client 2.3.1 if that helps.
----
2019-04-14 15:22:06 UTC - Cristian: Another worrying thing I saw is that, after the job stopped writing events for a couple of days, the Pulsar dashboard stopped showing my topics. I can still list them using `pulsar-admin topics list`

2019-04-15 08:40:07 UTC - Jianfeng Qiao: Anyone ever tried to compile pulsar on ARM platform?
----
2019-04-15 08:41:56 UTC - Ali Ahmed: you mean the java or c++ code ?
----
2019-04-15 08:45:13 UTC - Jianfeng Qiao: C++ code
----
2019-04-15 08:45:50 UTC - Jianfeng Qiao: Pulsar C++ client
----
2019-04-15 08:47:10 UTC - Ali Ahmed: No I haven’t tried it yet
