Small cell sizes use up loads of memory.  See HBASE-900 for more on this.
Other things to try:

+ hbase.io.index.interval is 32 by default.   Set it to 1024 or larger 
in your case.  Access may be a little slower -- but maybe not so bad 
since your cells are so small -- but the memory-resident indices will 
be smaller.
Oh, pardon me, this is broke in 0.18.x hbase.  See HBASE-981.  Changing 
the value has no effect.
