我需要将 Kafka 中的所有主题备份到以各自主题名称命名的文件中，并且需要根据用户要求恢复主题。注意：此脚本需要在 Kerberized 环境中运行。
kafkabackup.sh

monyear=`date | awk '{print $2$6}'`
dat=`date| awk '{print $2$3$6}'`
export BACKUPDIR=/root/backup/$monyear
mkdir -p $BACKUPDIR
mkdir -p $BACKUPDIR/$dat
cd $BACKUPSDIR
BKDIR=$BACKUPDIR/$dat
##Log into Kafka

##Get topics from Kafka Broker

kinit -kt /etc/security/keytabs/kafka.service.keytab kafka/node1.localdomaino@domain.co
cd /usr/hdp/current/kafka-broker/bin/
export KAFKA_CLIENT_KERBEROS_PARAMS="-Djava.security.auth.login.config=/etc/kafka/conf/kafka_client_jaas.conf"
./kafka-topics.sh --zookeeper adminnode.localdomain:2181 --list > $BKDIR/listtopics.txt

##Remove if any mark of deletion topics exists
sed -i.bak '/deletion/d' $BKDIR/listtopics.txt

## Starting kill script in parallel 

bash checkandkill.sh& 

##Reading the file contents for topics
for line in $(cat $BKDIR/listtopics.txt)
do
    echo $line
    ./test.sh --bootstrap-server node1.localdomain:6668 --topic $line  --consumer.config /home/kafka/conf.properties --from-beginning --security-protocol SASL_SSL > $BKDIR/$line
done

##Delete empty files

/usr/bin/find . -size 0 -delete

## Killing checkandkill daemon

ps -ef |grep -i checkandkill.sh| grep -v grep | awk '{print $2}' | xargs kill

exit

当消费者运行时，它会不断等待消息接收。我们需要终止进程。
checkandkill.sh

sleep 0.5m
for line in $(cat /root/backup/listtopics.txt)
do
    echo $line
    sleep 1m
    ps -ef |grep -i $line| grep -v grep | awk '{print $2}' | xargs kill
done

需要您的帮助来完成恢复脚本。
