Configuration Variable and ClassAd Attribute Additions and Changes:
- The default value of configuration variable
COLLECTOR_MAX_FILE_DESCRIPTORS has changed to 10240,
and the default value of configuration variable
SCHEDD_MAX_FILE_DESCRIPTORS has changed to 4096.
This increases the scalability of the default configuration.
(Ticket #3626).
- The new configuration variable
FILE_TRANSFER_DISK_LOAD_THROTTLE enables dynamic
adjustment of the level of file transfer concurrency in order to
keep the disk load generated by transfers below a specified level.
Supporting this new feature are configuration variables
FILE_TRANSFER_DISK_LOAD_THROTTLE_WAIT_BETWEEN_INCREMENTS ,
FILE_TRANSFER_DISK_LOAD_THROTTLE_SHORT_HORIZON , and
FILE_TRANSFER_DISK_LOAD_THROTTLE_LONG_HORIZON .
(Ticket #3613).
- The following new condor_schedd ClassAd attributes are for
monitoring file transfer activity:
TransferQueueMBWaitingToDownload,
TransferQueueMBWaitingToUpload,
FileTransferDiskThrottleLevel,
FileTransferDiskThrottleHigh, and
FileTransferDiskThrottleLow.
(Ticket #3613).
- The default value for the configuration variable
PASSWD_CACHE_REFRESH has been changed from 300 seconds to
72000 seconds (20 hours).
(Ticket #3723).
- The new configuration variables
DAGMAN_PEGASUS_REPORT_METRICS and
DAGMAN_PEGASUS_REPORT_TIMEOUT
set defaults used by the new condor_dagman_metrics_reporter executable,
which reports metrics for DAGMan jobs running under Pegasus.
(Ticket #3532).
Bugs Fixed:
- HTCondor version 8.0.0 had an unintended change in the Chirp
wire protocol.
This change caused condor_chirp with the put option
to fail when the execute node
was running HTCondor version 7.8.x or earlier versions.
HTCondor 8.0.1 and later
versions will now send the original wire protocol, and accept either the
original protocol, or the variant that HTCondor version 8.0.0 sends.
(Ticket #3735).
- Fixed a bug that could cause the daemons to crash on Unix platforms,
if the operating system reported that a job owner's account
did not exist, for example due to a temporary NIS or LDAP failure.
(Ticket #3723).
- Fixed a bug that resulted in a misleading error message when
condor_status with the -constraint option specified a constraint
that could not be parsed.
(Ticket #1319).
- Fixed a typo in the output of condor_q,
where a period was erroneously present within a heading.
(Ticket #3703).
