Below is my fair-scheduler.xml file:
<allocations>
<queue name="highPriority">
<minResources>100000 mb, 30 vcores</minResources>
<maxResources>500000 mb, 100 vcores</maxResources>
<weight>0.35</weight>
<minSharePreemptionTimeout>20</minSharePreemptionTimeout>
<fairSharePreemptionTimeout>25</fairSharePreemptionTimeout>
<fairSharePreemptionThreshold>0.8</fairSharePreemptionThreshold>
</queue>
<queue name="default">
<minResources>25000 mb, 20 vcores</minResources>
<maxResources>225000 mb, 70 vcores</maxResources>
<weight>0.14</weight>
<minSharePreemptionTimeout>20</minSharePreemptionTimeout>
<fairSharePreemptionTimeout>25</fairSharePreemptionTimeout>
<fairSharePreemptionThreshold>0.5</fairSharePreemptionThreshold>
<maxAMShare>-1.0f</maxAMShare>
</queue>
<queue name="ep">
<minResources>100000 mb, 30 vcores</minResources>
<maxResources>600000 mb, 100 vcores</maxResources>
<weight>0.42</weight>
<minSharePreemptionTimeout>20</minSharePreemptionTimeout>
<fairSharePreemptionTimeout>25</fairSharePreemptionTimeout>
<fairSharePreemptionThreshold>0.8</fairSharePreemptionThreshold>
<maxAMShare>-1.0f</maxAMShare>
</queue>
<queue name="vip">
<minResources>15000 mb, 20 vcores</minResources>
<maxResources>120000 mb, 30 vcores</maxResources>
<weight>0.09</weight>
<minSharePreemptionTimeout>20</minSharePreemptionTimeout>
<fairSharePreemptionTimeout>25</fairSharePreemptionTimeout>
<fairSharePreemptionThreshold>0.8</fairSharePreemptionThreshold>
<maxAMShare>-1.0f</maxAMShare>
</queue>
</allocations>
Since the root.ep queue and root.highPriority queue is so important that
anytime I don’t want them to be preempted.I know that if the resource of them
is preempted , their container maybe killed and thus it may take much more time
for applications running on them to finish.
So , Any solutions?
