Hello,

I am seeing "reloading region because regionserver didn't accept updates"
message in the middle of populating the table and was wondering what could
be wrong with it?

Thank you so much,

This is a client-side message right?

Usually it means that when we went to upload a batch, one or more of
the regions mentioned in the batch moved; the client has to find the
new location before it can retry what is left of the batch.

Hello Stack,

Thank you.
You are right, it's on the client side. I was populating 30 batches of
datasets one after another continuously to the same table, each batch
contains 100 rows with ~60000 cells in one column family. (Total: 3000 rows
with 60000 cells each row) The test cluster consists of low end old
machines. Could I increase the region size so that this could be avoided
because I am not very satisfied with the uploading speed ? What are the pros
and cons?

Thanks again :)

Take a look at this section of the book:
