Hi,
I am using flink 1.4.2 with rocksdb as backend. I am using process function
with timer on EventTime. For checkpointing I am using hdfs.
I am trying load testing so Iam reading kafka from beginning (aprox 7 days
data with 50M events).
My job gets stuck after aprox 20 min with no error. There after watermark do
not progress and all checkpoint fails.
Also When I try to cancel my job (using web UI) , it takes several minutes
to finally gets cancelled. Also it makes Task manager down as well.
There is no logs while my job hanged but while cancelling I get following
error.
