----------------------------------------------
Sample map-reduce export to export a single column family <columnFamilyName>
from <tableName> into <dir>. Output will be BLOCK compressed.
{code}
% bin/hadoop jar <pathToHBaseJar> export -D
hbase.mapreduce.scan.column.family=<columnFamilyName> -D
mapred.output.compress=true -D
mapred.output.compression.codec=org.apache.hadoop.io.compress.GzipCodec -D
mapred.output.compression.type=BLOCK <tableName> <dir>
{code}
Import:
{code}
% bin/hadoop jar /tmp/hbase-0.21.0-SNAPSHOT.jar import <tableName> <dir>
{code}
> HBase Export: Add ability to export specific Column Family; Turn Block Cache
> off during export; improve usage doc
