Examples of org.apache.hadoop.hbase.util.LoadTestKVGenerator.generateRandomSizeValue()

org.apache.hadoop.hbase.util.LoadTestKVGenerator.generateRandomSizeValue()
Generates a value for the given key index and column qualifier. Size is selected randomly in the configured range. The generated value depends only on the combination of the strings passed (key/cf/column/...) and the selected value size. This allows to verify the actual value bytes when reading, as done in {#verify(byte[], byte[]...)} This method is as thread-safe as Random class. It appears that the worst bug ever found with the latter is that multiple threads will get some duplicate values, which we don't care about.

    for (int i = 0; i < NUM_ROWS; ++i) {
      byte[] key = LoadTestKVGenerator.md5PrefixedKey(i).getBytes();
      for (int j = 0; j < NUM_COLS_PER_ROW; ++j) {
        Put put = new Put(key);
        byte[] col = Bytes.toBytes(String.valueOf(j));
        byte[] value = dataGenerator.generateRandomSizeValue(key, col);
        put.add(CF_BYTES, col, value);
        region.put(put);
      }
      if (i % NUM_ROWS_PER_FLUSH == 0) {
        region.flushcache();
