------------------------------------------------
[~jmhsieh]
Good find.
One suggestion
Instead of directly setting includeTags as true in LoadIncrementalHFiles - can
we see if
{code}
halfReader.getHFileReader().getFileContext().isIncludesTags()
{code}
And if that halfReader has tags then include the tags in the new Writer also?
Though not a problem - you can add a coprocessor and check for the presence of
tags on the server side itself after Incremental load instead of changing the
Rpc Codec. But that is also fine.
> bulkloading hfiles with tags that require splits do not preserve tags

> Components: HFile
> Affects Versions: 0.98.0, 1.0.0, 2.0.0, 1.1.0, 1.2.0, 1.3.0

> 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.
