My understanding is that in case I am using any of the hive/hdfs components then MR jobs are created and submitted on the Hive/Hadoop server.<BR />Let us say , I want to take read data from a Hive server, do some transformations and then load it into another Hive table. I can do it following way:<BR />Read the data from the Hive Table, use tMap to do the transformations, Load it into a Hive table<BR />How will data be processed in this case? Will a MR program be generated for all 3 components or will it be like data will be fetched on the server where talend job is running, then transformation will happen on that server?<BR />Basically what I want to know is that will all 3 components use the parallel processing power of the hive server or will there be any processing happening on the server where Talend job is running?</P> Sat, 16 Nov 2024 10:19:57 GMT https://community.qlik.com/t5/Talend-Studio/Hive-Query/m-p/2355621#M121333 Anonymous 2024-11-16T10:19:57Z https://community.qlik.com/t5/Talend-Studio/Hive-Query/m-p/2355622#M121334 Please help!
