> 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
> This bug is in both
> org.apache.hadoop.hbase.mapred.TableInputFormatBase
> org.apache.hadoop.hbase.mapreduce.TableInputFormatBase
