Hello,

Thank you for answer I have just altered my table and launched a
major_compact to get it effective.

I thought that increasing FILSIZE of HBases implies somehow changes on
the BLOSKSIZE of my tables and to prevent unbalanced paramaters
increased it too ... #FAIL.

The question is : in what application BLOCKSIZE should be changed
(increased or decreased) ?

Thank you.
