Dear All,

I have a requirement to read from text file input and write into multiple HBASE output using MapReduce. I am using Pentaho 4.4 version. Please help how to do this using MapReduce. Really appreciate if you could attach a sample for the same.

regards,
Rams

写个mapreduce的程序,去处理文本文件,在reduce以后将结果写到hbase,你可以使用hbase api 也可以采用hfile的方式将数据装载到hbase
将上述的程序打个jar包,然后写个shell调用这个jar包,最后kettle调用这个shell脚本。

I don't think that posting a reply in chinese is is ethically correct,

I don't mind it as the advice was on topic (even though I wouldn't advocate scripting if you have visual map/reduce available) but I would still advice folks to use the Big Data forum as it's read more by the members of the Pentaho Big Data team.

Hi, 

Thanks for the URL… 

I am looking for writing a MapReduce Job with the components available in pentaho without going to Java…

I am aware of MapReduce program writing to HDFS or HIVE.. but I need for HBASE.. really appreciate if you could suggest something on this..

If you need some sort of dedicated support, consider purchasing a Pentaho support contract.
This mailing list really is not the appropriate medium for your questions so please stop mailing now or I'll take appropriate action.

Thanks!

Matt
