> Key: HBASE-11010
> URL: https://issues.apache.org/jira/browse/HBASE-11010
> Project: HBase
> Issue Type: Bug
> Components: test
> Reporter: Lars Hofhansl
> Assignee: Lars Hofhansl
> Priority: Minor
> Fix For: 0.99.0, 0.94.19, 0.98.2, 0.96.3
>
> Attachments: 11010-0.94.txt, 11010-trunk.txt

> 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.
