Subject RE: Data loading from Datanode
Date Thu, 08 Dec 2011 08:24:54 GMT
Hi Vikas,

 

I think there is some problem in understanding, I have my cluster setup
where I have installed Hive on namenode, and I can insert data into HDFS
using hive.

 

My question is, can I install hive on any of the datanode (instead of
namenode) and load data from there in datanode directly? And once I do a
data insertion from datanode (and to datanode) the master syncs with
datanode later and keeps track of newly added file on datanode.

 

Kind Regards,

Keshav C Savant

hey

yes its possible to load data through hive in hadoop, but you can't
decide that where data file should  store(on which node). that could
only be decide by namenode.

So that means can we insert files into datanode directly (or from hive
installed on datanode) and then the master node syncs with datanodes
later.
