TableInputFormat should support more confs for the scanner
----------------------------------------------------------
Key: HBASE-2095
URL: https://issues.apache.org/jira/browse/HBASE-2095
Project: Hadoop HBase
Issue Type: Improvement
Components: mapreduce
Affects Versions: 0.20.2
Reporter: Bassam Tabbara
Fix For: 0.20.3
TableInputFormat currently only supports hbase.mapreduce.scan and
hbase.mapreduce.inputtable confs. The scan conf is a Base64 encoded scanner
object, which makes it difficult to use TIF from hadoop pipes. I propose that
the following confs be supported iff hbase.mapreduce.scan is not set:
* hbase.mapreduce.scan.columns
* hbase.mapreduce.scan.timestamp
* hbase.mapreduce.scan.timerange.start
* hbase.mapreduce.scan.timerange.end
* hbase.mapreduce.scan.maxversions
* hbase.mapreduce.scan.cacheblocks
* hbase.mapreduce.scan.cachedrows
Ideally we would also support filters but I think that would be harder to
implement.
