Hello,
According to a hadoop tutorial (http
://wiki.apache.org/nutch/NutchHadoopTutorial) on wiki,
"you don't want to search using DFS, you want to search
using local filesystems.
Once the index has been created on the DFS you can use the
hadoop
copyToLocal command to move it to the local file system as
such".
So
my understanding is that hadoop is only good for batch index
building,
and is not proper for incremental index building and search.
Is this
true? By "incremental index building and search",
I mean a system that
accepts text on the fly, builds index and makes the index
available
for search immediately.
cheers,
Paul
