Xintong Song closed FLINK-14869. -------------------------------- Fix Version/s: 1.13.0 Resolution: Fixed Fixed via * master (1.13): 72841d77802746dc12bffb5927ae0e43a681cb98 > Force an extended resource to be null if it's value is 0 > -------------------------------------------------------- > > Key: FLINK-14869 > URL: https://issues.apache.org/jira/browse/FLINK-14869 > Project: Flink > Issue Type: Sub-task > Components: Runtime / Coordination > Affects Versions: 1.10.0 > Reporter: Zhu Zhu > Assignee: Xintong Song > Priority: Major > Labels: pull-request-available > Fix For: 1.13.0 > > > {{Resource}} accepts value 0 at the moment because 0 {{CPUResource}} is used > in production to indicate no strict requirement for CPU cores. > However, keeping extended resources with value 0 is causing troubles. > e.g. There can be 2 ResourceSpecs, rs1 and rs2, with the same resources > except that rs1 contains a GPUResource with value 0 while rs2 does not > contains a specified GPUResource. In this case, rs1.equals(rs2)==false and > rs1.isLessOrEqualThan(rs2)==false, which is not correct. > Accepting both 0 and null extended resources is also making things more > complex, since we need to consider it in all > comparisons(equals/lessThanOrEqual/isMatch) and aggregations(merge/subtract). > To be simple, I'd propose to change it like this: in > ResourceSpec/ResourceProfile we only keep extended resource with positive > values. To be specific, if in the constructors of > ResourceSpec/ResourceProfile, a specified extended resource is found to be 0, > it must be dropped so that 0 resource would always be null. > cc [~chesnay] -- This message was sent by Atlassian Jira (v8.3.4#803005)
