------------------------------------
Summary: DUCC RM: Reenable purge bit
Key: UIMA-3129
URL: https://issues.apache.org/jira/browse/UIMA-3129
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jim Challenger
Assignee: Jim Challenger
Fix For: 1.0-Ducc
We had disabled RM's 'purge' bit because of a race with the Agent. Changes to
the agent eliminate the race.
The 'purge' bit is set when a machine misses some number of heartbeats. RM
considers the node "down" and evict the shares, similar to preemption. Without
the 'purge' bit the OR will wait for confirmation from agents that the
processes are stopped, but if the agent is not responding, the confirmation may
never come and the processes will be "stuck".
The 'purge' bit is used to tell OR that the shares are being evicted because of
suspected agent death, so OR can clean up right away and not look for
confirmation.
