--------------------------------------------------------------

Josh does have it pretty much covered - I'll work up some text that refers to that section if the missing file is in the metadata table.

Question: How does one create an empty rfile?  I have one that has been passed down from my grandmother's second cousin's aunt and has been in the family for generations, but how would I create a new one?  I thought I could just create an new table, but that does not seem to generate a file.

Is it possible using the shell (using 1.5.1standard dist) with:

create table sample1
insert row1 colf colq value1
delete row1 colf colq 
flush

This gives me something like:

\-rw\-r\-\-r\-\-   1 hdfs supergroup        199 2014-04-06 09:51 /accumulo/tables/2/default_tablet/F000000q.rf

Or should it be done using AccumuloOutputFormat?
