apache-kafka - 错误 org.apache.kafka.common.errors.InvalidReplicationFactorException：

Question

在cloudera VM 5.13中运行命令时，您能否帮我解决以下错误

[cloudera@quickstart ~]$ sudo service kafka-server startStarting Kafka Server (kafka-server): [OK ]

[cloudera@quickstart ~]$

我已经根据 cloudera 网站的以下链接使用命令行步骤安装了 kafka：
https ://www.cloudera.com/documentation/kafka/latest/topics/kafka_installing.html

请找到以下额外的 zookeeper 详细信息：

    # The id of the broker. This must be set to a unique integer for each broker.
    broker.id=0

    # Switch to enable topic deletion or not, default value is false
    #delete.topic.enable=true

    ############################# Socket Server Settings #############################

    # The address the socket server listens on. It will get the value returned from
    # java.net.InetAddress.getCanonicalHostName() if not configured.
    #   FORMAT:
    #     listeners = listener_name://host_name:port
    #   EXAMPLE:
    #     listeners = PLAINTEXT://your.host.name:9092
    #listeners=PLAINTEXT://:9092

    # Hostname and port the broker will advertise to producers and consumers. If not set,
    # it uses the value for "listeners" if configured.  Otherwise, it will use the value
    # returned from java.net.InetAddress.getCanonicalHostName().
    #advertised.listeners=PLAINTEXT://your.host.name:9092

    # Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details

    # The number of threads handling network requests

    socket.receive.buffer.bytes=102400

    # The maximum size of a request that the socket server will accept (protection against OOM)
    socket.request.max.bytes=104857600


    ############################# Log Basics #############################

    # A comma seperated list of directories under which to store log files
    log.dirs=/tmp/kafka-logs

    # The default number of log partitions per topic. More partitions allow greater
    # parallelism for consumption, but this will also result in more files across
    # the brokers.
    num.partitions=1

    # The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.
    # This value is recommended to be increased for installations with data dirs located in RAID array.
    num.recovery.threads.per.data.dir=1

    ############################# Log Flush Policy #############################

    # Messages are immediately written to the filesystem but by default we only fsync() to sync
    # the OS cache lazily. The following configurations control the flush of data to disk.
    # There are a few important trade-offs here:
    #    1. Durability: Unflushed data may be lost if you are not using replication.
    #    2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.
    #    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to exceessive seeks.
    # The settings below allow one to configure the flush policy to flush data after a period of time or
    # every N messages (or both). This can be done globally and overridden on a per-topic basis.

    # The number of messages to accept before forcing a flush of data to disk
    #log.flush.interval.messages=10000

    # The maximum amount of time a message can sit in a log before we force a flush
    #log.flush.interval.ms=1000

    ############################# Log Retention Policy #############################

    # The following configurations control the disposal of log segments. The policy can
    # be set to delete segments after a period of time, or after a given size has accumulated.
    # A segment will be deleted whenever *either* of these criteria are met. Deletion always happens
    # from the end of the log.

    # The minimum age of a log file to be eligible for deletion due to age
    log.retention.hours=168

    # A size-based retention policy for logs. Segments are pruned from the log as long as the remaining
    # segments don't drop below log.retention.bytes. Functions independently of log.retention.hours.
    #log.retention.bytes=1073741824

    # The maximum size of a log segment file. When this size is reached a new log segment will be created.
    log.segment.bytes=1073741824

    # The interval at which log segments are checked to see if they can be deleted according
    # to the retention policies
    log.retention.check.interval.ms=300000

    ############################# Zookeeper #############################

    # Zookeeper connection string (see zookeeper docs for details).
    # This is a comma separated host:port pairs, each corresponding to a zk
    # server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
    # You can also append an optional chroot string to the urls to specify the
    # root directory for all kafka znodes.
    zookeeper.connect=localhost:2181

    # Timeout in ms for connecting to zookeeper
    zookeeper.connection.timeout.ms=6000

你的--zookeeper设置不正确。它应该是--zookeeper quickstart.cloudera:2181而不是--zookeeper quickstart.cloudera:2181/kafka。我刚刚通过使用尾随复制了这个错误/kafka并删除了它解决了这个问题。
