Hi Ram, We're attempting to do it programmatically so:
The HFile is created by a Spark job using saveAsNewAPIHadoopFile, and using ImmutableBytesWritable as the key (rowkey) with KeyValue as the value, and using the HFilOutputFormat2 format. This HFile is then loaded using HBase client's LoadIncrementalHFiles.doBulkLoad Is there a way to do this programmatically without using the ImportTsv tool? I was taking a look at VisibilityUtils.createVisibilityExpTags and maybe being able to just create the Tags myself that way (although it's obviously @InterfaceAudience.Private) but it seems to be able to use that I'd need to know Label ordinality client side.. Thanks for your help, Tom -----Original Message----- From: ramkrishna vasudevan [mailto:ramkrishna.s.vasude...@gmail.com] Sent: 07 June 2016 11:19 To: user@hbase.apache.org Subject: Re: Writing visibility labels with HFileOutputFormat2 -- This email has reached the Bank via an external source -- Hi Ellis How is the HFileOutputFormat2 files created? Are you using the ImportTsv tool? If you are using the ImportTsv tool then yes there is a way to specify visibility tags while loading from the ImportTsv tool and those visibility tags are also bulk loaded as HFile. There is an attribute CELL_VISIBILITY_COLUMN_SPEC that can be used to indicate that the data will have Visibility Tags and the tool will automatically parse the specified field as Visibility Tag. In case you have access to the code you can see the test case TestImportTSVWithVisibilityLabels to get an initial idea of how it is being done. If not get back to us, happy to help .
