[jira] Created: (HBASE-1865) 0.20.0 TableInputFormatBase NPE

0.20.0 TableInputFormatBase NPE
-------------------------------

                 Key: HBASE-1865
                 URL: https://issues.apache.org/jira/browse/HBASE-1865
             Project: Hadoop HBase
          Issue Type: Bug
    Affects Versions: 0.20.0
            Reporter: Eric Tschetter


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.
