Bill Graham commented on CHUKWA-533:
------------------------------------
All tests pass except these which I suspect are failing for unrelated reasons:
build/test/TEST-org.apache.hadoop.chukwa.datacollection.TestOffsetStatsManager.txt:Tests
run: 3, Failures: 1, Errors: 0, Time elapsed: 13.1 sec
build/test/TEST-org.apache.hadoop.chukwa.rest.resource.TestClientTrace.txt:Tests
run: 1, Failures: 1, Errors: 0, Time elapsed: 4.201 sec
build/test/TEST-org.apache.hadoop.chukwa.rest.resource.TestUserResource.txt:Tests
run: 2, Failures: 1, Errors: 1, Time elapsed: 2.881 sec
TestHBaseWriter also fails, but that's because all tests are commented out.
I'll commit this patch shortly.

> There are currently a number of ways that a collector can die, typically due
> to errors on a DN or a NN that's being restarted. A collector should have
> some combination of retry logic followed by failing back to the agent, but
> the collector process should not die.
