txt文件导入kafka

shell脚本导入

#!/bin/sh
## 参数定义
dt=`date +"%Y%m%d" -d "-1 days"`
outpath=/home/etl/test/test.txt   
brokerlist='kakfa卡集群地址'

echo $dt $outpath $brokerlist
## 判断文件大小，如果大于0，则加载文件，写入kafka
## 注意 结尾的 | > out.txt要加上，否则会出现很多奇怪的大于号
fileSize=`du -b ${outpath} | awk '{print $1}'`
if [ $fileSize -gt 0 ] 

then
    cat ${outpath} | /usr/local/kafka/bin/kafka-console-producer.sh --broker-list ${brokerlist} --sync --topic health_doc_tag_history_test | > out.txt
