Hari Shreedharan updated HBASE-9093:

    Attachment: HBASE-9093.patch

SVN formatted patch. Sorry about this, seems like patch can't apply a git diff when a new
file is added. This patch applies:
patch -p0 < HBASE-9093.patch 
patching file hbase-client/src/test/java/org/apache/hadoop/hbase/client/TestPutWriteToWal.java
patching file hbase-client/src/main/java/org/apache/hadoop/hbase/client/Mutation.java

> The writeToWal is used by downstream projects like Flume to disable writes to WAL to
improve performance when durability is not strictly required. But renaming this method to
setDurability forces us to use reflection to support hbase versions < 95 - which in turn
hits performance, as this method needs to be called on every single write. I recommend adding
the old method back as deprecated and removing it once hbase-95/96 becomes the popular version
used in prod.
