Hadoop 2 to Hadoop 3 Rolling Upgrade feasibility

2022-12-16 Thread Nishtha Shah
Hi team,

While I am checking on feasible upgrade plans for this major upgrade, A
quick check if someone was able to perform a successful rolling upgrade
from Hadoop 2 to Hadoop 3.

I have gone through a couple of articles online which are suggesting to opt
for Express Upgrade and avoid Rolling upgrade. A quick check if someone was
able to successfully do a rolling upgrade in recent years.

References I have gone through:

Any leads/responses are appreciated.
