Subject Re: Slow HBase write across data center

Try to figure out which region server is handling those writes and it could
be possible that particular region server is skewing your cluster's write

Another thing to check if your data is already skewed across regions/region

Once I faced this issue, I enabled multiwal and used table presplitting
according to my keyspace and it fixed the region write performance.
