> I'm using Flink 1.8.0 version and have enabled externalized checkpoint to hdfs location,
we have seen few scenarios where checkpoint folders will have checkpoint files but only missing
"*_metadata*" file. If we attempt to restore application from this path, application fails
with exception "Could not find *_metadata* file. There is similar discussion in Flink user
mailing list with subject  "Zookeeper connection loss causing checkpoint corruption" around
it. I've attached sample snapshot on how folder structure looks as well.
