Description
When an iterator is configured to run during a one-time manual major compaction on a tablet that is empty, the iterator never runs. It seems as if Accumulo never constructs the SKVI stack at all, because it tries to optimize by eliminating "unnecessary" tablet compactions. Also true of MiniAccumulo.
This is bad for "generator" iterators that emit keys (in sorted order) not present in the tablet's data. They never have a chance to run.
A workaround is for the client to insert "dummy data" into the tablets he wants to compact, before starting a compaction with "generator" iterators. Note that any data is sufficient, even delete keys, to ensure the SKVI stack is built and run through.
Test file: InjectTest
- method testInjectOnCompact_Empty fails because no data is in the tablets
- method testInjectOnCompact passes because data is written into the tablets before initiating compaction.
Two logs follow. Both have a DebugIterator set after an InjectIterator, an SKVI which "generates" hard-coded entries. The root user scans the table after flush and compact.
Logs when no data in the tablets:
