Jean-Marc Spaggiari updated HBASE-8521:
---------------------------------------
Attachment: HBASE-8521-v4-addendum-0.94.patch
So here is the culprit.
There is now an extra parameter to the bulkLoadHFiles call where we need to
specify the assignSeqNum boolean. However, the mocked connection was still
configured to fail on the method call without this parameter (which is not the
one being called).
This addendum is to update the mocked connection configuration.
Passed the test locally. Sorry for this.

> Let's say you have a pre-built HFile that contains a cell:
> ('rowkey1', 'family1', 'qual1', 1234L, 'value1')
> We bulk load this first HFile. Now, let's create a second HFile that contains
> a cell that overwrites the first:
> ('rowkey1', 'family1', 'qual1', 1234L, 'value2')
> That gets bulk loaded into the table, but the value that HBase bubbles up is
> still 'value1'.
> It seems that there's no way to overwrite a cell for a particular timestamp
> without an explicit put operation. This seems to be the case even after minor
> and major compactions happen.
> My guess is that this is pretty closely related to the sequence number work
> being done on the compaction algorithm via HBASE-7842, but I'm not sure if
> one of would fix the other.
