Hello, I think I get only some results as input for my hadoop job based on the log below. I there any way how to wait for the scan longer or am I missing something else? ``` 2016-01-31 02:03:47,073 INFO [main] com.aerospike.hadoop.mapreduce.AerospikeRecordReader: queue empty: waiting... 2016-01-31 02:03:48,074 INFO [main] com.aerospike.hadoop.mapreduce.AerospikeRecordReader: queue empty: waiting... 2016-01-31 02:03:49,074 INFO [main] com.aerospike.hadoop.mapreduce.AerospikeRecordReader: queue empty: waiting... 2016-01-31 02:03:50,074 INFO [main] com.aerospike.hadoop.mapreduce.AerospikeRecordReader: queue empty: waiting... 2016-01-31 02:03:51,075 INFO [main] com.aerospike.hadoop.mapreduce.AerospikeRecordReader: queue empty: waiting... 2016-01-31 02:03:52,075 ERROR [main] com.aerospike.hadoop.mapreduce.AerospikeRecordReader: SCAN TIMEOUT 2016-01-31 02:03:52,080 INFO [main] org.apache.hadoop.mapred.MapTask: Starting flush of map output ``` ---

I discovered where was the problem. My code threw unhandled exception and the job stuck. So it was my fault, hadoop client is working nicely.
