Jesse Yates commented on HBASE-5304:
------------------------------------
bq. I can add a section to the HBase book (reference guide) with
PrefixSplitKeyPolicy as an example
Can you do both? This would be a good start to that Tips and Tricks section
that has been mentioned recently.
bq. The splitKey is always validated against the region before the actual
split. If it is not valid you get an error message (see HRegion.checkSplit and
SplitTransaction.prepare) and the split is not performed. Falling back to the
default instead might invalidate other assumptions that the application code
had based on the provided SplitPolicy.
Good call. +1 on that and everything else.
