Re: Hadoop upgrade, what happend on Datanode side and how long can it takes?
Hello Norbert,

In 2.x, the upgrade process on the DN disk layout happens with greater
parallelism, and the overall DN upgrade is also a distributed task, so
you can expect it to complete very fast - certainly less than an hour
tops.
