Yuan Kang commented on HBASE-17124:
-----------------------------------

I have see HBASE-14123 ,it's used for Backup/Restore,and I can't find HFileInputFormat in
the patchs.HFileInputFormat can be used for analyze.  simplly,people can flush a table,then
run a mapreduce job with HFileInputFormat ,this can analyze data online just like the function
TableMapper do

> HFileInputFormat can help user read hbase table with HFile way,more effective

> When we need to read large amount of data from hbase,usually we use tableinputformat
to query hbase table. but hfileInputFormat way is more effective
