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

             Summary: TestChangingEncoding is unnecessarily slow
                 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: 0.94.19


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.
