Question

生成的reassignment.json

/home/ubuntu/deploy/kafka/bin/kafka-reassign-partitions.sh --zookeeper 127.0.0.1:2181 --generate --topics-to-move-json-file /home/ubuntu/deploy/kafka/topics_to_move.json --broker-list '<broker-list>' |tail -1 > /home/ubuntu/deploy/kafka/reassignment.json

执行重新分配

/home/ubuntu/deploy/kafka/bin/kafka-reassign-partitions.sh --zookeeper 127.0.0.1:2181 --execute --reassignment-json-file /home/ubuntu/deploy/kafka/reassignment.json

我在kafka 1.1.0中更改了以下主题

/home/ubuntu/deploy/kafka/bin/kafka-topics.sh --zookeeper 127.0.0.1:2181 --alter --topic Topic3 --config min.insync.replicas=2

但是只要我想验证重新分配，如下所示

/home/ubuntu/deploy/kafka/bin/kafka-reassign-partitions.sh --zookeeper 127.0.0.1:2181 --reassignment-json-file /home/ubuntu/deploy/kafka/reassignment.json --verify

它显示了以下异常

我从经纪人处获得的server.properties如下

############################# Server Basics #############################

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

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

# The port the socket server listens on
port=9092

# Hostname the broker will bind to. If not set, the server will bind to all interfaces
#host.name=localhost

# Hostname the broker will advertise to producers and consumers. If not set, it uses the
# value for "host.name" if configured.  Otherwise, it will use the value returned from
# java.net.InetAddress.getCanonicalHostName().
#advertised.host.name=<hostname routable by clients>

# The port to publish to ZooKeeper for clients to use. If this is not set,
# it will publish the same port that the broker binds to.
#advertised.port=<port accessible by clients>

# 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 #############################

log.dirs=/var/lib/kafka/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.

# 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
log.retention.hours=36

# 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.
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=536870912

# 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

# By default the log cleaner is disabled and the log retention policy will default to just delete segments after their retention expires.
# If log.cleaner.enable=true is set the cleaner will be enabled and individual logs can then be marked for log compaction.
log.cleaner.enable=false

############################# 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=platform1:2181,platform2:2181,platform3:2181

message.max.bytes=15000000
replica.fetch.max.bytes=15000000

auto.create.topics.enable=true

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

// Indicates whether to enable replicas not in the ISR set to be elected as leader as a last resort, even though doing so may result in data loss
unclean.leader.election.enable=false

// Disable Topic Deletion
delete.topic.enable=false

############################# Internal Topic Settings  #############################
# The replication factor for the group metadata internal topics “__consumer_offsets” and “__transaction_state”
# For anything other than development testing, a value greater than 1 is recommended for to ensure availability such as 3.
# Currently These properties are not used as we do not use these topic.

在Kafka 0.10中正常工作的流程相同。有人可以让我知道怎么了吗？在Kafka 1.1.0中有与此相关的任何更改吗？

Answer 1

为什么不尝试从json文件中删除所有"log_dirs": ["any"]。此“ log_dirs”是可选的。

此外，如果要保留log_dirs字段，请尝试以下格式。您的log_dir计数应与副本数相同。

{"partitions": [{"topic": "foo", "partition": 1, "replicas": [1,2,3], "log_dirs": ["any","any","any"] }], "version":1 }
