--------------------------------------
Summary: Initiate graceful shutdown of impala daemon by sending a
signal to the process
Key: IMPALA-8401
URL: https://issues.apache.org/jira/browse/IMPALA-8401
Project: IMPALA
Issue Type: Bug
Reporter: Bikramjeet Vig
Assignee: Bikramjeet Vig
Once the shut down process is initiated, impalad would stop accepting any new
connections or queries. This makes it difficult if a user wants to shut down
impalad across a cluster via the shutdown command. For eg. the user would need
to make sure to send the command to all executors before sending them to the
coordinators. Adding a mechanism to initiate the graceful shutdown process with
a large deadline by sending a SIGQUIT to the impalad process would make cluster
management simpler.
