Question

我可以将流程部署到Apache Flink的独立安装（带有一个JobManager和几个TaskManager），没有问题：

bin/flink run -m example-app-1.stag.local:6123 -d -p 4 my-flow-fat-jar.jar <flow parameters>

但是当我运行相同的命令并部署到独立HA群集时，此命令会引发错误：

------------------------------------------------------------
 The program finished with the following exception:

活动作业管理器将以下错误写入日志：

2016-04-14 13:54:44,160 WARN  akka.remote.ReliableDeliverySupervisor                        - Association with remote system [akka.tcp://flink@127.0.0.1:62784] has failed, address is now gated for [5000] ms. Reason is: [Disassociated].
2016-04-14 13:54:46,299 WARN  org.apache.flink.runtime.jobmanager.JobManager                - Discard message LeaderSessionMessage(null,TriggerSavepoint(5de582462f334caee4733c60c6d69fd7)) because the expected leader session ID Some(72630119-fd0a-40e7-8372-45c93781e99f) did not equal the received leader session ID None.

所以，我不明白什么会导致这样的错误？

如果需要其他信息，请告诉我。

P.S。

从Flink Dashboard部署适用于独立HA群集。当我仅通过Flink CLI进行部署时会出现此类问题。

更新

我清除Zookeeper，清除Flink在磁盘上使用的目录并重新部署Flink Standalone HA群集。然后我尝试运行flow use bin/flink run命令。正如您所看到的，JobManager只写了一行关于问题的内容（请参阅flink - jobmanager-0-example-app-1.stag.local.log）。

所有JobManagers和TaskManagers使用相同的flink-conf.yaml：

jobmanager.heap.mb: 1024
jobmanager.web.port: 8081

taskmanager.data.port: 6121
taskmanager.heap.mb: 2048
taskmanager.numberOfTaskSlots: 4
taskmanager.memory.preallocate: false
taskmanager.tmp.dirs: /flink/data/task_manager

blob.server.port: 6130
blob.storage.directory: /flink/data/blob_storage

parallelism.default: 4

state.backend: filesystem
state.backend.fs.checkpointdir: s3a://example-flink/checkpoints

restart-strategy: none
restart-strategy.fixed-delay.attempts: 2
restart-strategy.fixed-delay.delay: 60s

recovery.mode: zookeeper
recovery.zookeeper.quorum: zookeeper-1.stag.local:2181,zookeeper-2.stag.local:2181,zookeeper-3.stag.local:2181
recovery.zookeeper.path.root: /example/flink
recovery.zookeeper.storageDir: s3a://example-flink/recovery
recovery.jobmanager.port: 6123

fs.hdfs.hadoopconf: /flink/conf

因此，似乎正确配置了独立HA群集。

更新2

仅供参考：我想按照here所述安装独立HA群集。不是YARN HA集群。

更新3

以下是bin/flink CLI创建的日志：flink-username-client-hostname.local.log。

Answer 1

在HA模式下启动Flink群集时，JobManager地址及其领导者ID将写入指定的ZooKeeper群集。为了与JobManager进行通信，您不仅要知道地址，还要知道其领导地址。因此，您必须在CLI中读取的＆lt; flink-conf.yaml`中指定以下参数。

recovery.mode: zookeeper
recovery.zookeeper.quorum: address of your cluster
recovery.zookeeper.path.root: ZK path you've started your cluster with

通过此信息，客户端知道它可以在哪里找到ZooKeeper集群以及在哪里找到JobManager地址及其领导者ID。

无法使用Flink CLI将流部署到Apache Flink的HA集群
