      Work Description: supratimdeka commented on issue #841: HDDS-1559. Include committedBytes
to determine Out of Space in VolumeChoosingPolicy. Contributed by Supratim Deka
URL: https://github.com/apache/hadoop/pull/841#issuecomment-495488583
 
 
   the checkstyle errors reported here are not a part of this patch. these were introduced
in SCMContainerPlacementRackAware.java by HDDS-700 and got submitted into trunk yesterday.
   
   I think we can ignore these checkstyle errors reported for this patch because they already
exist on the main branch. Right?

> This is a follow-up from HDDS-1511 and HDDS-1535
> Currently  when creating a new Container, the DN invokes RoundRobinVolumeChoosingPolicy:chooseVolume().
This routine checks for (volume available space > container max size). If no eligible volume
is found, the policy throws a DiskOutOfSpaceException. This is the current behaviour.
> However, the computation of available space does not take into consideration the space
> that is going to be consumed by writes to existing containers which are still Open and
accepting chunk writes.
> This Jira proposes to enhance the space availability check in chooseVolume by inclusion
of committed space(committedBytes in HddsVolume) in the equation.
> The handling/management of the exception in Ratis will not be modified in this Jira.
That will be scoped separately as part of Datanode IO Failure handling work.
