Subject [jira] [Created] (HBASE-15035) bulkloading hfiles with tags that require splits does not preserve tags
Date Wed, 23 Dec 2015 19:46:46 GMT
Jonathan Hsieh created HBASE-15035:
--------------------------------------

             Summary: bulkloading hfiles with tags that require splits does not preserve tags
                 Key: HBASE-15035
                 URL: https://issues.apache.org/jira/browse/HBASE-15035
             Project: HBase
          Issue Type: Bug
          Components: HFile
    Affects Versions: 1.1.0, 1.0.0, 2.0.0
            Reporter: Jonathan Hsieh
            Priority: Blocker


When an hfile is created with cell tags present and it is bulk loaded into hbase the tags
will be present when loaded into a single region.  If the bulk load hfile spans multiple regions,
bulk load automatically splits the original hfile into a set of split hfiles corresponding
to each of the regions that the original covers.  

Since 0.98, tags are not copied into the newly created split hfiles. (the default for "includeTags"
of the HFileContextBuilder [1] is uninitialized which defaults to false).   This means acls,
ttls, mob pointers and other tag stored values will not be bulk loaded in.
