Description

I was running some testing on a already busy cluster and my clients in the mappers sometimes aren't able to create an HTable because of ConnectionLoseException. The code logs that as an error but still continues with a null HTable then this happens:

java.lang.NullPointerException
	at org.apache.hadoop.hbase.mapreduce.TableRecordReaderImpl.restart(TableRecordReaderImpl.java:58)
	at org.apache.hadoop.hbase.mapreduce.TableRecordReaderImpl.init(TableRecordReaderImpl.java:67)
	at org.apache.hadoop.hbase.mapreduce.TableRecordReader.init(TableRecordReader.java:57)
	at org.apache.hadoop.hbase.mapreduce.TableInputFormatBase.createRecordReader(TableInputFormatBase.java:108)

Needs to be prettier.
