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

             Summary: AbstractNode field `inBufSize` is unused
                 Key: IGNITE-21702
                 URL: https://issues.apache.org/jira/browse/IGNITE-21702
             Project: Ignite
          Issue Type: Bug
            Reporter: Viacheslav Blinov


Issue detected by SpotBugs. Specifically the warning reported is:
{noformat}
M C EC_UNRELATED_TYPES_USING_POINTER_EQUALITY EC: Using pointer equality to 
compare a org.apache.calcite.rel.RelDistributions$RelDistributionImpl with a 
org.apache.ignite.internal.sql.engine.trait.IgniteDistribution in new 
org.apache.ignite.internal.sql.engine.rel.IgniteSender(RelOptCluster, 
RelTraitSet, RelNode, long, long, IgniteDistribution)  At 
IgniteSender.java:[line 58]
{noformat}
It looks like a bug because this comparsion will always yield false!

Investigate whenever this is a false-positive and we should suppress it, or 
make a proper fix.

At the result of investigation corresponding TODO should be removed in 
spotbugs-excludes.xml
