Flink multiple task managers setup
Hi ,
I am unable to set two task managers in my local machine and neither any
documentation provided for the same.
I want to run a parallel job in two task managers using flink.
kindly help me with the same, how can i set up in my local without using
any zookeeper or something.
Thanks & Regards,
Saksham Sapra

Hi,
As the error message said, it could not find the flink-dist.jar in
"/cygdrive/d/Apacheflink/dist/apache-flink-1.9.3/deps/lib". Where is
your flink distribution and do you change the directory structure of
it?
Best,

Hi,
It seems you run it in Windows. In that case, only start-cluster.bat
could be used. However, this script could only start one TM[1] no
matter how you configure the slaves/workers.

Hi,
> I wasnt having "workers" file in conf/workers so i created one, but i have "slaves" file in conf/workers, so i edited both two localhost like screenshot given below :
Yes, for 1.9.3, you need to edit the 'slaves' file.
I think we need more information to figure out what happened.
- What is the output when you execute ./bin/start-cluster.sh, could
you see two "Starting taskexecutor daemon on host" lines?
- Could you see two flink-xxx-taskexecutor-xxx.log in $FLINK_DIST/log?
If so, could you share these two log files?

Hi,
From my understanding, you want to set up a standalone cluster in your
local machine. If that is the case, you could simply edit the
$FLINK_DIST/conf/workers, in which each line represents a TM host. By
default, there is only one TM in localhost. In your case, you could
add a line 'localhost' to it. Then, execute the
$FLINK_DIST/bin/start-cluster.sh, you could see a standalone cluster
with two TM in your local machine.
