Gour Saha commented on SLIDER-1197:
-----------------------------------
[~sseth] this is what I did for the pending allocations and last allocation
time. Note, the yarn mem available is coming in the next commit for this jira.
Pending allocations can be retrieved from Slider status output as below -
At component level (existing feature):
{noformat}
roles.<COMPONENT_NAME>.(yarn.component.instances - role.actual.instances)
{noformat}
At overall application level, across all components (newly added) -
{noformat}
liveness.requestsOutstanding
{noformat}
A new attribute has been added to the liveness blob to provide the last
allocation time, e.g. -
{code}
"liveness" : {
"allRequestsSatisfied" : false,
"requestsOutstanding" : 1,
"activeRequests" : 0,
"lastAllocationTime" : 1487094509702
}
{code}
Note, allRequestsSatisfied is false when one or more requests are outstanding.
