We have a HDP 2.4.2 cluster experiencing TEZ 3297 issues with AM deadlock. Support is suggesting me to either upgrade to 2.5.0 or do a hotfix. On what basis do i decide which to chose when i have time constraints. Suppose, when you have exisiting jobs in 2.4.2 and u upgrade to 2.5, then to check if the same jobs are running the same way without issues in 2.5.0... usually how long is the validation period? to say that there are no issues with the jobs... any suggestions?
