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)
