-------------------------------------------
Summary: Striped pool starvation check reports false-positive
warnings if a job starts right before the check
Key: IGNITE-10225
URL: https://issues.apache.org/jira/browse/IGNITE-10225
Project: Ignite
Issue Type: Bug
Reporter: Stanislav Lukyanov
StripedExecutor::checkStarvation checks if two conditions are met: a stripe is
executing a job and the stripe's job counter hasn't changed since the last
check.
These conditions will be met if no jobs have been executed for a long time and
a job (even a very short one) has just started.
This check isn't supposed to be exact and allowed to produce false-positives.
However, the check is supposed to detect jobs running for more than starvation
check interval (IGNITE_STARVATION_CHECK_INTERVAL), but in this case it may
detect even very short ones.
To fix this we may require a stripe to have no progress in two consecutive
checks - then we will have much less chance for a false-positive, but still
detect hanging or very long jobs.
