ok .thanks a lot that information . As i said i am running 2 datanodes on same machine . so my haddop home has 2 conf folders . conf and conf2 and in turn 2 hdfs-site.xml in both conf folders . I guess dfs.replication value in hdfs-site.xml of conf folder should be 3 . What should i have it in conf2 ? should it be 1 there ?
sorry if question sounds stupid . But i am unfamiliar with these kind of settings ( 2 datanodes on same machine ..so having 2 conf ) If data is split across multiple datanodes , then processing capacity would be improved - ( thats what i guess ) since my file is only 240 KB , it occupies only one block . It cannot use second block and remain in another datanode . So now , does it make sense to reduce the block size so that blocks are split between 2 datanodes —if i want to take very much advantage of multiple datanodes . Any advices ? Your help would be appreciated . Best Regards, Sindhu
