{code}
Typo: regionb
{code}
+ * As and example, if you have row keys delimited with <code>_</code>, like
{code}
Typo: and
{code}
+ * ensures that all rows staring with the same userid, belongs to the same
region.
{code}
Typo: staring, belongs
Please add stability annotation.
{code}
+ //find the first occurrence of delimiter in split point
{code}
The above comment should be explicitly mentioned in class javadoc where
delimiter appears twice in rowkey:
{code}
+ * <code>userid_eventtype_eventid</code>, and use prefix delimiter _, this
split policy
{code}
