Error migrating to 1.6

[Juan Gentile]

Hello!

 

We are trying to migrate from 1.4 to 1.6 and we are getting the following exception in our jobs:

org.apache.flink.util.FlinkException: The assigned slot container_e293_1539164595645_3455869_01_011241_2 was removed.

Do you know the reason? Any help is appreciated.

 

Thank you,
