server/base/src/main/java/org/apache/accumulo/server/fs/PreferredVolumeChooser.java <https://reviews.apache.org/r/28873/#comment107345> I think that optimization is good, but this was intended to be an example of how users could use a PerTableVolumeChooser. Because of this I think that the simplier version is better for easy reading and using it as a guide for their own choosers. - Jenna Huston On Dec. 10, 2014, 2:58 p.m., Sean Busbey wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
