Subject Null source for iterator
Date Thu, 27 Feb 2014 18:36:30 GMT
Given this code :

BatchScanner scanner = connector.createBatchScanner("tableName", authorizations, threadCount);

IteratorSetting iterSetting = new IteratorSetting(10, "filterName", CustomFilter.class);

iterSetting.addOption("option1", "value1");

iterSetting.addOption("option2", "value2");


Iterator<Entry<Key,Value>> iter = scanner.iterator();


I am receiving this exception when hasNext() is called :

2014-02-27 15:47:08,845 [thrift.ProcessFunction] ERROR: Internal error processing startMultiScan

java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.IllegalStateException:
getting null source

The full stacktrace can be found at

If anyone can shed light on what I am doing wrong, I would deeply appreciate it.
