--------------------------------------
Summary: Index read repair should delete all the cells of an
invalid unverified row
Key: PHOENIX-5615
URL: https://issues.apache.org/jira/browse/PHOENIX-5615
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.14.3, 5.0.0
Reporter: Kadir OZDEMIR
In the current implementation, the index read repair deletes only the cells
that are returned by the scan initiated by the Phoenix client instead of
deleting all the cells of an invalid unverified row.
The read repair deletes cells (i.e., a specific version of a row) only when if
an index row is overwritten but the corresponding data table row overwrite
fails. This leaves the the index row in the unverified status. Then the read
repair detects this unverified row when it is scanned and needs to delete the
cells of this unverified version of the row. However, the read repair (i.e.,
GlobalIndexChecker) puts the delete markers for only the cells returned by the
scan. If the scan does not return all the cells of the row, then only a subset
of the cells of the row will be deleted. The remaining cells will not be
removed and can be returned by the scans initiated later.
