David Medinets commented on ACCUMULO-251:
-----------------------------------------

>From A. Fuchs on the mailing list: I think the confusion here might be that 
>there are two different operations called "flush". One is the flush of the 
>BatchWriter's local buffer, and the other is the flush of the TabletServer's 
>in-memory map (AKA minor compaction). This example refers to the latter. There 
>are also auto-flushes in both cases, but the flush in this case is effectively 
>forcing the minor-compaction operation with a known quantity of data.

This information might also be useful in the README.bloom file.
                
> Add wording to README.bloom about reason for flushing.

> The README.bloom file says this:
>  * Insert 1 million entries using  RandomBatchWriter with a seed of 7
>  * Flush the table using the shell
>  * Insert 1 million entries using  RandomBatchWriter with a seed of 8
>  * Flush the table using the shell
>  * Insert 1 million entries using  RandomBatchWriter with a seed of 9
>  * Flush the table using the shell
> However, no reasons are given for why three flushes are used instead of one. 
> Please explain the reasons.
