Kafka-Connect-Hdfs - 无法启动 HdfsSinkConnector

Question

我已经从 http://docs.confluent.io/2.0.0/quickstart.html#quickstart

下载了 kafka connect

我正在尝试 运行 hdfs 连接器。 以下是设置：

连接-standalone.properties:

bootstrap.servers=lvpi00658.s:9092,lvpi00659.s:9092,lvpi00660.s:9092

key.converter=org.apache.kafka.connect.storage.StringConverter
value.converter=org.apache.kafka.connect.storage.StringConverter

internal.key.converter=org.apache.kafka.connect.storage.StringConverter
internal.value.converter=org.apache.kafka.connect.storage.StringConverter

offset.storage.file.filename=/tmp/connect.offsets
# Flush much faster than normal, which is useful for testing/debugging
offset.flush.interval.ms=10000

key.deserializer=org.apache.kafka.common.serialization.StringDeserializer
 value.deserializer=org.apache.kafka.common.serialization.StringDeserializer

和

快速入门-hdfs.properties:

name=hdfs-sink
connector.class=io.confluent.connect.hdfs.HdfsSinkConnector
tasks.max=1
topics=eightball-stuff11
hdfs.url=hdfs://localhost:9000
flush.size=3

我 运行 hdfs 连接器是这样的：
cd /home/fclvappi005561/confluent-3.0.0/bin
./connect-standalone ../etc/kafka-connect-hdfs/connect-standalone.properties ../etc/kafka-connect-hdfs/quickstart-hdfs.properties

但我得到一个错误：

我应该提到我在 127.0.0.1 本地 运行 一个 docker hadoop 映像：docker run -d -p 9000:9000 sequenceiq/hadoop-docker:2.7.1

我看到的这个权限被拒绝错误是什么？我所在的主机与 bootstrap.servers

下提到的主机不同

Answer 1

权限被拒绝的错误是在hdfs端。用户 "root" 没有对 hdfs 目录“/topics”的写入权限。
