It is for the duration of the restart. The concern is what will happen to
any reads which is inflight that is using the data node. Will HDFS client
know the offset to start reading from where the read failed using another
DN?

How long would your datanode be out of service ?
If the duration is long (say 1 day), you'd better decommission it first.
Otherwise, datanode restart can be done without going through
decommissioning.

Hello There,
Can individual datanodes restarted (through service command) or do we
need to add it to the exclude file in NN, restart DN it, remove it from the
exclude file in NN as if the data node is being decommissioned and put
back? Any feedback on this is much appreciated.
Thanks,
Biju
