Grokbase Groups HBase dev April 2010
Add scanner caching option to Export and write buffer option for Import

Key: HBASE-2434
Project: Hadoop HBase
Issue Type: Improvement
Components: util
Affects Versions: 0.20.3
Reporter: Ted Yu

An option of number of rows to fetch every time we hit a region server should be added to mapreduce.Export so that createSubmittableJob() calls s.setCaching() with the specified value.

Also, an option of write buffer size should be added to mapreduce.Import so that we can set write buffer. Sample calls:
+ table.setAutoFlush(false);
+ table.setWriteBufferSize(desired_buffer_size);
