Siddharth Seth commented on HIVE-13858: --------------------------------------- The test failures are unrelated. This particular run took over 4 hours compared to other runs which take 2 hours. However, from the logs it looks like the mvn build started at 23:00, and the test run completed at 01:19 - which is a 2h20m and consistent with other runs. Looks to be a delay in the run actually starting. Committing. > LLAP: A preempted task can end up waiting on completeInitialization if some > part of the executing code suppressed the interrupt > ------------------------------------------------------------------------------------------------------------------------------- > > Key: HIVE-13858 > URL: https://issues.apache.org/jira/browse/HIVE-13858 > Project: Hive > Issue Type: Bug > Affects Versions: 2.0.0 > Reporter: Siddharth Seth > Assignee: Siddharth Seth > Priority: Blocker > Labels: llap > Attachments: HIVE-13858.01.patch, HIVE-13858.02.patch, > HIVE-13858.03.patch > > > An interrupt along with a HiveProcessor.abort call is made when attempting to > preempt a task. > In this specific case, the task was in the middle of HDFS IO - which > 'handled' the interrupt by retrying. As a result the interrupt status on the > thread was reset - so instead of skipping the future.get in > completeInitialization - the task ended up blocking there. > End result - a single executor slot permanently blocked in LLAP. Depending on > what else is running - this can cause a cluster level deadlock. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
