Hello Stack

I just read your post, thank you very much for answering.

Indeed, you were right: this is reference to 
hbase.ipc.IndexedRegionInterface
which was the problem. Either running trunk 0.92 or 0.91 
with Sun/OpenJDK VM's
seems to work.

I am gonna read further documentation on HBase architecture, and 
have a deep
look at CoProcessor feature, in order to understand how secondary 
indexing or
custom aggregations can be handled by HBase.

Best regards

Jerome
