1. Please make sure IGFS is really used: e.g. you may explicitly locate some
table data on IGFS, and run the queries upon. IGFS statistics can partially
be observed through Visor. 
Also please note, that upon node(s) start IGFS is empty. In case of dual
modes it caches the data upon file reading. In case of primary mode you need
to put some data onto the file system before you can use it. So, data read
performance boost can be seen only when some data are already cached in
IGFS, and read from there rather than from disk. 

2. Can you specify data and the query , so that we could reproduce the
issue? (E.g. you can use some publicly available sample data from Hive

3. No. The nodes should connect without additional effort. Can you please
attach full logs of all nodes where this situation happens?
