Hi, community
I see the checkpointLock is used in StreamTask to ensure that we don't have
concurrent method calls that void consistent checkpoints.
As i known, it is used in the data consume , state interactive and the
timerService, But I am doubt that, if an application don't enable the

Hi,
It is recommended to always call update().
State modifications by modifying objects is only possible because the heap
based backends do not serialize or copy records to avoid additional costs.
Hence, this is rather a side effect than a provided API. As soon as you
change the state backend, st
Hi,
Flink InputFormats generate their InputSplits sequentially on the
JobManager.
These splits are stored in the heap of the JM process and handed out to
SourceTasks when they request them lazily.
Split assignment is done by a InputSplitAssigner, that can be customized.
FileInputFormats typically
How often is the warning logged? The default reporting interval is 10
seconds, if a report is interrupted it can take a while for metrics to
show up.
Could this also be caused by the MAX_CREATES_PER_MINUTE setting in
carbon.conf being set too low?

We are aware of YARN-2031. There are some ideas how to workaround it, which
are tracked here:

there are at least 3 main players which use the lock to sync state access
between each other:
thread processing records in user code, checkpointing thread and processing
timers callback thread.
I would still recommend to follow the contract and use the lock where required

Hello, I am a new user for flink jira. I reported an issue and would like
to fix it, however I found I could not assign it to myself, or anyone.
Is there anyone to tell me how to do this?
Thanks.
Hi,
I've given you Contributor permissions for Jira and assigned the issue to
you.
You can now also assign other issue to you.
Looking forward to your contribution.

Thanks for the details. I got it working. I have around 1 directory for
each month and I am running for 12-15 month data.So I created a dataset
from each month and did a union.
However, when I run I get the HTTP timeout issue. I am reading more than
120K files in total in all of months.

Hi Juho,
It seems in your case the JobMaster did not receive a heartbeat from the
TaskManager in time [1]. Heartbeat requests and answers are sent over the
RPC
framework, and RPCs of one component (e.g., TaskManager, JobMaster, etc.)
are
dispatched by a single thread. Therefore, the reasons for he

I'm trying to write to a Kafka stream in a Flink job using the new Python
streaming API.
My program looks like this:

Hi Johe,
In local mode, it should also work.
When you debug, you can set a breakpoint in the getCurrentWatermark method
to see if you can enter the method and if the behavior is what you expect.
What is your source? If you post your code, it might be easier to locate.
In addition, for positioning

Hi,
I have stream_A of type "Dog", which needs to be transformed using data from
stream_C of type "Name_Mapping". As stream_C is a slow one (data is not
being updated frequently), to do the transformation I connect two streams,
do a keyBy, and then use a RichCoFlatMapFunction in which mapping data
Hi Averell,
As far as these two solutions are concerned, I think you can only choose
option 2, because as you have stated, the current Flink DataStream API does
not support the replacement of one of the input stream types of
CoFlatMapFunction. Another choice:
1. Split it into two separate jobs. B
As seen in the stacktrace every sink added via StreamExEnv#add_source is
wrapped in a PythonSinkFunction which internally converts things to
PyObjects, that's why the mapper had no effect.
Currently we don't differentiate between java/python sinks, contrary to
sources where we have an explicit
Hi Averell,
I am also in favor of option 2. Besides, you could use CoProcessFunction
instead of CoFlatMapFunction and try to wrap elements of stream_A and stream_B
using the `Either` class.
Best,
