Zhijie Shen updated MAPREDUCE-5231:
-----------------------------------
Attachment: MAPREDUCE-5231.1.patch
Added the following constructor back to DBInputFormat.DBRecordReader in mapred.
{code}
protected DBRecordReader(DBInputSplit split, Class<T> inputClass, JobConf job)
throws SQLException
{code}
The constructor uses the variables of DBInputFormat in mapreduce to fill the
additional constructor params. To achieve it, these variables are changed to
protected.
> Constructor of DBInputFormat.DBRecordReader in mapred is changed

> The constructor of DBInputFormat.DBRecordReader in mapred is changed from MR1
> to RM2. Though MAPREDUCE-716 tried to deal with the API difference. However,
> if DBInputFormat.DBRecordReader is extended, the incompatibility around the
> constructor is still there.
