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

This a good idea. Which versions HDFS support this?

> In HDFS we use sync_file_range(WRITE) to periodically sync data to disks to ensure we
have smooth IO and not huge bursts to the disk. We need to allow HBase to enable sync_file_range(WAIT_AFTER
| WRITE) to ensure that HFiles are throttled and can write only as fast as disks can.
