Subject [jira] [Updated] (HBASE-11821) [ImportTSV] Abstract labels tags creation into pluggable Interface
Date Tue, 02 Sep 2014 11:10:21 GMT

     [ https://issues.apache.org/jira/browse/HBASE-11821?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Anoop Sam John updated HBASE-11821:
-----------------------------------
       Resolution: Fixed
    Fix Version/s:     (was: 0.98.7)
                   0.98.6
     Release Note: 
Added a facade org.apache.hadoop.hbase.mapreduce.CellCreator to create Cells for HFileOutputFormat.
When working with HFileOutputFormat (with or with out visibility labels) in bulk load one
can  use this facade to make Cells with visibility tags.
Also we allow plugin an implementation of org.apache.hadoop.hbase.mapreduce.VisibilityExpressionResolver
by configuring the the FQCN with key "hbase.mapreduce.visibility.expression.resolver.class".
The default implementation will tag Cells with visibility label ordinal.

     Hadoop Flags: Reviewed
           Status: Resolved  (was: Patch Available)

> HBASE-11553 abstracted out the VisibilityLabelService and using which one can go with
String based labels tags instead of default ordinal based. In MapReduce side, ImportTSV also
should support such an abstraction layer.  This is applicable for HFileOutputFormat where
mappers create Cells to be written to HFiles. 
> Also every Mapper (custom written also) dealing with such low level HBase things (Creation
of tags and Cells) is not a good idea. This issue plan to provide a public audience Facade
class to facilitate such Cell creation so that Mappers can just make use of them.
