我想通过 Oozie 安排 Hbase Map-Reduce 作业。我面临以下问题。
How/Where to specify these properties in oozie workflow ?
( i> Table name for Mapper/Reducer
ii> scan object for Mapper )
Scan scan = new Scan(new Get());
scan.setMaxVersions();
scan.addColumn(Bytes.toBytes(FAMILY),
Bytes.toBytes(VALUE));
scan.addColumn(Bytes.toBytes(FAMILY),
Bytes.toBytes(DATE));
Job job = new Job(conf, JOB_NAME + "_" + TABLE_USER);
// These two properties :-
TableMapReduceUtil.initTableMapperJob(TABLE_USER, scan,
Mapper.class, Text.class, Text.class, job);
TableMapReduceUtil.initTableReducerJob(DETAILS_TABLE,
Reducer.class, job);
或者
please let me know the best way to schedule a Hbase Map-Reduce Job by Oozie .
谢谢 :) :)
