    If the data size written by Hadoop app is small, i.e. data size : (a) before any of HFlush/HSync call is made or (b) between 2 HFlush/Hsync API calls is less than write buffer size, 2 separate calls, one for append and another for flush are made. By enabling the small write optimization, a single call will be made to perform both append and flush operations and hence reduce request count.

    When parquet files are read, first few read are metadata reads before reading the actual data.
