The Hadoop name node GetFile Operation slowing down the job performance

While the dataset is getting generated, the segmented files with zero byte gets created first then the process start filling the data on the segmented files sequentially. If there isn’t enough volume to fill all the 8 segments ( CSDP uses 8 segments ), then the segmented files are left empty. While during the read operation, these zero byte files are getting read by Hadoop NN and cause an overhead to GetFile Operation during the peak hours. Can this design will be changed to create the segmented files only if there is a record to fill ? This will reduce the creation of zero byte files and reduce the IO overhead.
