Key: LIVY-800
URL: https://issues.apache.org/jira/browse/LIVY-800
Project: Livy
Issue Type: Bug
Components: Server
Affects Versions: 0.5.0
Environment: Redhat_7.4 8memories,4cores
Reporter: mrpencil
Fix For: 0.5.0
Attachments: 1.jpg, 2.jpg
Livy does not release resources, resulting in the number of file handles
exceeding. Please see the attached picture.
Error content: *too many open files.*
This will cause an error to be reported after Livy has been running for a
period of time, and the session can no longer be created.
*Another problem is* that on my 8g memory, 4-core RedHat server, I tried many
parameter combinations, and finally found that I can only run 18 sessions at
the same time. Exceeding this value will cause more than half of the sessions
to die. Is there any way to increase the concurrency value?
