Data ingestion using kafka from crawlers

hadoopNoob — Fri, 16 Sep 2022 13:35:48 GMT

Hello,

I am trying to work with kafka for data ingestion but being new to this, i kind of pretty much confused.

I have multiple crawlers, who extract data for me from web platforms, now the issue is i want to ingest that extracted data to hadoop using kafka without any middle scripts/service file . Main commplication is that, platforms are disparate in nature and one web platform is providing real-time data other batch based. Can integrate my crawlers some how with kafka producers ? and they keep running all by themselves. is it possible ? I think it is but i am not getting in right direction. any help would be appreciated.

Thanks

Hello,

Loading data directly to Kafka without any Service seems unlikely.

However, you can use execute a simple kafka console producer to send all your data to the kafka service. But if your requirement is to save data to HDFS you need to include a few more services along with Kafka.

For example, Crawlers >> kafka console producer (or) Spark Streaming >> Flume >> HDFS

As your requirement is to store the data in HDFS and not stream the data. I suggest you execute a Spark job, it will store your data to HDFS. Refer mentioned commands to execute a spark job to move data to HDFS.

Initiate a spark-shell

Execute the mentioned command in the Spark shell in the same order.

val moveFile = sc.textFile("file:///path/to/Sample.log")

moveFile.saveAsTextFile("hdfs:///tmp/Sample.log")
