--------------------------------------
Summary: Index read repair does not repair unverified rows with
higher timestamp
Key: PHOENIX-5505
URL: https://issues.apache.org/jira/browse/PHOENIX-5505
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.14.3, 5.0.0, 4.15.0
Reporter: Kadir Ozdemir
Read repair (GlobalIndexChecker) sets the time range for the scan on the data
table for using the timestamp of the index table row to be repaired. The start
time for the scan is the timestamp of the index row in the current
implementation. However, if the index row timestamp is higher than the data
table row timestamp, then the data table row will not be visible to the scan.
The index row timestamp can be higher when the index row is overwritten with
the unverified row status (in the first write phase) but the data table row is
not overwritten (in the second write phase) due to a failure. In this case, the
unverified index row will not be rebuilt and will be deleted eventually.
