Zhijie Shen commented on YARN-906:
----------------------------------
Did some investigation in this test failure. The test itself seems to have no
problem. The test was timeout because the container state kept RUNNING after it
was stopped, which was not expected.
Looked into the test log: after stopContainer was called, Container moved from
LOCALIZED to KILLING, but didn't move on any more. However, looked into my
local test log of a successful run: Container moved from LOCALIZED to KILLING,
and then from KILLING to CONTAINER_CLEANEDUP_AFTER_KILL, during which the major
work is to clean the localized container resources (observed the execution of
file deletion). However, the failed test log didn't show any file deletion.
Therefore, I guess there's something blocking during container resources
cleanup. Thoughts?
More investigation is needed to further locate the problem.
