Subject [jira] [Commented] (IGNITE-8697) Flink sink throws java.lang.IllegalArgumentException when running in flink cluster mode.

Ray commented on IGNITE-8697:
-----------------------------

Hello [~samaitra],
 
Thanks for the fix.
I validated this fix by running my WordCount application in both standalone
mode and cluster mode.
The data can be inserted.
 
But I found another problem here.
The data written into Ignite is not correct.
My application counts the word occurrence in this the following sentence.
         "To be, or not to be,--that is the question:--",
         "Whether 'tis nobler in the mind to suffer",
         "The slings and arrows of outrageous fortune",
         "Or to take arms against a sea of troubles,
 
The count of word "to" should be 9.
But when I check the result in Ignite, all the values of every word is 1.
Clearly it's wrong.
The reproducer program is the same as I attached above.
 
Please let me know if you can reproduce this issue.
