https://github.com/apache/accumulo/pull/176
> May want to point out https://issues.apache.org/jira/browse/HDFS-3702 as
an option starting with Hadoop 2.8, so that if the node goes down and can't be
brought back up, you can still recover using the WAL.
@dlmarion what you are suggesting seems like it would require a lot of
context to explain. I don't know how to write that context up. I would be
happy to add anything you write up or you could write up a following blog post
and I can review it. I am thinking we can build up a body of useful info and
ideas w/ blog post, and blog post can reference other post to avoid repeating
contextual info.
For the improvements sections I was also thinking of mentioning that
another possible solution to this would be to use the multiple tservers per
node you added AND a custom balancer that assigns tablets based on durability
settings. However I decided not add this information because I though it would
take too much to explain well. This could also be another blog post. I was not
really sure what to do this idea... I couldn't even decided if it was a good a
idea or not.
