Thanks for the clarification [~stevenz3wu].
I looked at the code again and I think [~trohrmann] is right. The order of
heartbeat timeouts is because TMs don't request heartbeats, only respond.

Steven Zhen Wu commented on FLINK-19401:
[~roman_khachatryan] I don't know if repeated checkpoint recovery is the
root/main cause or not. [~trohrmann] identified two problems during his
investigation. This is one of the identified problem.
Regarding the logs related to Titusm please ignore them. They are just noise.
We haven't cleaned up our logs yet.

I do see that the same data is downloaded over and over, but I'm not sure
whether it's the root cause.
From the logs I see that heartbeat from *on JM* from TMs are expired first,
and heartbeat *on TMs* expire two minutes later:
{code:java}
flink-19401 $ grep -ah -B1 'Heartbeat of Task' *.log | grep '^2020' | cut -c-16
| sort | uniq -c
66 2020-09-18 23:57

flink-19401 $ grep -ah -B1 'heartbeat of Job' *.log | grep '^2020' | cut -c-16
| sort | uniq -c

2 2020-09-19 00:37
2 2020-09-19 01:06
{code}
(77 vs 517 is due to parallelism level I think)
Furthermore, the first 8 recoveries start after failures in Kafka: NPE in
NetworkClient and "SSLProtocolException: Handshake message sequence violation,
2".
Then they happen after Kafka failures and the aforementioned TM heartbeat
timeouts on JM.
So it looks like that the root cause is misconfiguration and/or network.
WDYT [~trohrmann], [~stevenz3wu] ?
Steven, can you please also explain what does this mean:

No, the 3 operator chains are recovered together. However, we do this operation
for every subtask index which means that we read the checkpoints
{{parallelism}} times.

Steven Zhen Wu commented on FLINK-19401:
[~trohrmann] just to clarify, do you mean operator chain caused the repeated
checkpoint recoveries? i.e. if an operator chain has 3 operators, we are
repeating checkpoint recoveries 3 times no matter the 3 operators has state or
not.
In this job, only two Kafka sources and the co-process functions have state. It
has 3 operator chains as Till described (two operator chains for source, one
operator chain for co-process+sink).

In the logs it looks as if you also have an embarrassingly parallel part:
Several sources which are chained with a flat map and then two filters which
are chained with a process function and sinks. I believe that this part causes
the repeated checkpoint recoveries.
