> 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:
> {noformat}
> 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)
> {noformat}
> Needs to be prettier.
