Arpit Agarwal resolved HDDS-1559. --------------------------------- Resolution: Fixed Fix Version/s: 0.5.0 Target Version/s: (was: 0.5.0) I've committed this to trunk. Thanks for the contribution [~sdeka]. > Include committedBytes to determine Out of Space in VolumeChoosingPolicy > ------------------------------------------------------------------------ > > Key: HDDS-1559 > URL: https://issues.apache.org/jira/browse/HDDS-1559 > Project: Hadoop Distributed Data Store > Issue Type: Improvement > Components: Ozone Datanode > Reporter: Supratim Deka > Assignee: Supratim Deka > Priority: Major > Labels: pull-request-available > Fix For: 0.5.0 > > Time Spent: 1h 50m > Remaining Estimate: 0h > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
