I am trying to create a unit test using the HBaseClusterTestCase and the
I am able to spin up a hbase table, load data inside, access the data
(lookup and scan), but whenever I am trying to launch a map/reduce job
(TableMapper), the map/reduce functions are never executed because the
number of splits returned byt the TableInputFormat is empty. After some
debugging, I noticed that the line (in TableInputFormatBase)
final byte  startKeys = table.getStartKeys();
is returning an empty array.
In fact, even if I am able to access table data using HTable#get, the
HTable#getStartKeys is returning nothing. Any ideas on this issue ?
Also, do someone have some advices/examples on how to write and run unit
tests involving hbase ?
