Andras Gyori updated YARN-10236:
--------------------------------
Attachment: YARN-10236.001.log
Description:
A LogAggregation cycle might interrupt an in-progress logging. Chance of this
is happening is low, however, not zero. Due to this race condition, a log entry
could be entirely discarded, without being written to the log file.
Tested with specifications:
* Kerberos + SSL enabled
* TFile + Rolling log aggregation
The log file misses the 58th entry due to this behaviour.
