Eric Tschetter updated HBASE-1865:
----------------------------------
Description:
Spot the bug in this code:
public List<InputSplit> getSplits(JobContext context) throws IOException {
byte [][] startKeys = table.getStartKeys();
if (startKeys == null || startKeys.length == 0) {
throw new IOException("Expecting at least one region.");
}
if (table == null) {
throw new IOException("No table was provided.");
}
...
}
Should check if the table is null before calling a method on it.
Admittedly, this isn't the worst bug in the world, it's really just more of a
nuisance in that the "No table was provided" message becomes an NPE
