Release Note:
Adds MultiTableInputFormat.
Usage example:
{code}
Scan scan1 = new Scan();
scan1.setStartRow(start1);
scan1.setStopRow(end1);
Scan scan2 = new Scan();
scan2.setStartRow(start2);
scan2.setStopRow(end2);
MultiTableInputCollection mtic = new MultiTableInputCollection();
mtic.Add(tableName1, scan1);
mtic.Add(tableName2, scan2);
TableMapReduceUtil.initTableMapperJob(mtic, TestTableMapper.class, Text.class,
IntWritable.class, job1);

If you would rather close this issue or start a new one that is fine just let me know. Here is what I have done from the previous version, * Removed random formatting changes * Removed table.close() in TableRecordReaderImpl * Replaced MultiTableInputCollection with List * Brought up to date with trunk Remaining questions, * Since most of enum Version code is copied, we may want to factor the base enum to its own class. Would org.apache.hadoop.hbase.util be a good namespace for the enum class ? * The changes to TableSplit would not allow a new version of it to be deserialized by an old server. Is that OK for a M/R job? * It has been mentioned to scope this to scans (of a single table) rather then multiple tables. I can't seem to get the tests to run for me (getting OOM errors) but I would imagine most everything still works. > Support multiple tables and scanners as input to the mapper in map/reduce jobs > -- > > Key: HBASE-3996 > URL: https://issues.apache.org/jira/browse/HBASE-3996 > Project: HBase > Issue Type: Improvement > Components: mapreduce >Reporter: Eran Kutner >Assignee: Lars Hofhansl > Fix For: 0.96.0, 0.94.5 > > Attachments: 3996-v2.txt, 3996-v3.txt, 3996-v4.txt, 3996-v5.txt, > 3996-v6.txt, 3996-v7.txt, 3996-v8.txt, HBase-3996.patch > > > It seems that in many cases feeding data from multiple tables or multiple > scanners on a single table can save a lot of time when running map/reduce > jobs. > I propose a new MultiTableInputFormat class that would allow doing this. -- This message is automatically generated by JIRA.
