Users should be able to choose custom TableInputFormats without modifying
TableMapReduceUtil.initTableMapperJob().

Key: HBASE-4039
URL: https://issues.apache.org/jira/browse/HBASE-4039
Project: HBase
Issue Type: New Feature
Components: mapreduce
Affects Versions: 0.90.3
Environment: HBase-0.90.3. OS, hardware specs not relevant.
Reporter: Edward Choi
Priority: Minor
Currently,
org.apache.hadoop.hbase.mapreduce.TableMapReduceUtil.initTableMapperJob()forces
any Hbase job to use the default TableInputFormat.class as the job's input
format class.
"job.setInputFormatClass(TableInputFormat.class);" ==> This line is included in
initTableMapperJob().
This restriction causes users to modify initTableMapperJob() in addition to
implementing their own TableInputFormat.
It would be nicer if users can use custom TableInputFormats without
additionally tampering with HBase source code.
