Aljoscha Krettek commented on FLINK-5415:
-----------------------------------------
Inserting a {{Thread.sleep(200)}} in
{{ContinuousFileMonitoringFunction.monitorDirAndForwardSplits()}} will make the
tests fail reliably. Normally, it occurs now and then due to "natural" slow
downs on Travis:
log: https://api.travis-ci.org/jobs/199977242/log.txt?deansi=true
The condition that wait's for the file monitoring function to reach a certain
state needs to be tougher.
