Hi Manish, Are you sure this is an exception that’s actually killing the job?
Asking because https://issues.apache.org/jira/browse/BEANUTILS-477 <https://issues.apache.org/jira/browse/BEANUTILS-477> talks about Commons Beanutils logging this exception, but it’s a warning vs. something being thrown up the stack. — Ken > On May 15, 2019, at 3:50 PM, Manish Bellani <manish.bell...@gmail.com> wrote: > > hey Friends, > > Thanks for all the work you have been doing on flink, I
