Igfs and MaprFs
Hi,
On the ignite site, it does have links that talk about running igfs on top
of Apache hadoop, hdp and cdh but there is no mention of MapR ... Is it due
to the no namenode architecture of MapR that it is not supported?
Pls advise

No, IGFS will not work without that URL. I'm not sure how
com.mapr.fs.MapRFileSystem
exactly works, but I suppose that you can specify any MapR Fs node host
there.
One of possible ideas is to specify "localhost" as the 2ndary Fs URI,
assuming each host running Ignite node is a MapR Fs node. Though, such
configuration should be checked for correct work in practice.

Thx Ivan ...
Thr is a parameter for uri for class ignitehadoopigfssecondaryfilesystem in
the config which is for specifying namenode host and port .. in case of
MapR shud we leave it empty then?

Hi, Pranay,
IGFS can run upon any file system that can be represented in terms of Hadoop
file system API (namely as a org.apache.hadoop.fs.FileSystem).
MapR file system also implements Hadoop file system API , namely, it has
com.mapr.fs.MapRFileSystem .
So, IGFS can successfully run upon.
Though, it may also be true that in such mode Ignite will not be able to
utilize all MapR Fs advantages, because Ignite does not have native
integration with MapR Fs .
