10.3 Stable Release Series 8.6
This is a stable release series of HTCondor.
As usual, only bug fixes (and potentially, ports to new platforms)
will be provided in future 8.6.x releases.
New features will be added in the 8.7.x development series.
The details of each version are described below.
Version 8.6.0
Release Notes:
- HTCondor version 8.6.0 released on January 26, 2017.
New Features:
- Added two new job classad attributes, CumulativeRemoteSysCpu and
CumulativeRemoteUserCpu, which keep a running total of system and user
cpu usage, respectively, across all job restarts. Also, immediately clear attributes
RemoteSysCpu and RemoveUserCpu on job start, instead of on first update.
(Ticket #6022).
- Added a new config knob, ALWAYS_REUSEADDR, which defaults
to True. When True, it tells HTCondor to set the
SO_REUSEADDR socket option, so that
the schedd can run large numbers of very short jobs without exhausting the
number of local ports needed for shadows.
(Ticket #6040).
- Changed the default value of IGNORE_LEAF_OOM to True.
(Ticket #5775).
Bugs Fixed:
- Fixed a bug causing unnecessarily slow updates from the condor_startd.
If you depend on the old behavior, set UPDATE_SPREAD_TIME to 8. A
value of 0 enables the fix.
(Ticket #6062).
- Fixed a race condition when running multiple concurrent jobs on the same claim.
When the starter exits, it notifies the shadow, which tells the startd to kill the starter.
Immediately after the shadows tells the startd, it fetches the next job, and tries to start it.
If the starter hasn't completely exited yet (perhaps it needs to clean up a large sandbox),
it will notice the shadow has closed the command socket, and the starter will go into disconnected
mode, and get confused. This has been fixed.
(Ticket #6049).
- Fixed an infelicity with condor_submit -i and docker universe,
where it would start an interactive shell without a container. Added error
message expressing that this combination is not currently supported.
(Ticket #6083).
- When a job claimed by the Job Router is held or removed, it is no
longer considered a failure of the job route chosen for that job.
(Ticket #5968).
- Fixed a bug in recovering a Google Compute Engine (GCE) job if the
condor_gridmanager restarts during submission of the instance request.
(Ticket #6078).
- Fixed a bug that could cause re-installation of a remote cluster
to fail in Bosco.
(Ticket #6042).
- Fixed a bug with handling the proxy files of grid-type batch jobs
when the proxy's filename is a relative path.
(Ticket #6053).
- Fixed a bug that caused the batch_gahp to crash when a job's
X.509 proxy is refreshed and the batch_gahp is configured to not
create a limited copy of the proxy.
(Ticket #6051).
- Fixed a bug in the virtual machine universe where RequestMemory
and RequestCPUs were not changing the resources assigned to the VM
created by HTCondor. Now, VM_Memory defaults to RequestMemory,
and the number of CPUs defaults to RequestCPUs.
(Ticket #5998).
