>            Reporter: Lars Hofhansl

>            Priority: Minor
>             Fix For: 0.99.0, 0.94.19, 0.98.2, 0.96.3

> The test runs for over 10m on the Jenkins boxes.
> Writing the test data is done like this:
> {code}
>     for (int i = 0; i < NUM_ROWS_PER_BATCH; ++i) {
>       Put put = new Put(getRowKey(batchId, i));
>       for (int j = 0; j < NUM_COLS_PER_ROW; ++j) {
>         put.add(CF_BYTES, getQualifier(j),
>             getValue(batchId, i, j));
>         table.put(put);
>       }
>     }
> {code}
> There are two problems:
> # the same Put is "putted" multiple times (once for each column added)
> # each Put issued this way causes its one RPC
> On my machine changing this bring the runtime from 247s to 169s.
