----------------------------------------
Summary: index ScannerBuilder builds filter list not compatible
with HBase 1.4
Key: PHOENIX-4687
URL: https://issues.apache.org/jira/browse/PHOENIX-4687
Project: Phoenix
Issue Type: Bug
Reporter: Sergey Soldatov
This is related to IndexMetadataIT#testMutableTableOnlyHasPrimaryKeyIndex
failure on the master branch.
in ScannerBuilder we are building the list of filters for indexes:
1. columns filter
2. timestamp filter
3. delete tracker
Later to produce the scanner we are running a kv scanner with this filter and
returns EmptyScanner or CoveredDeleteScanner basing on the result.
In case if columns list is empty, the behavior of the filter's
filterAllRemaining() has been changed.
In 1.3 it returns true, in 1.4 it returns false and let FilterList to proceed
to the next filter. As the result instead of getting EmptyScanner we are
building CoveredDeleteScanner.
We may unify the case and in case of an empty list of columns we may explicitly
return EmptyScanner. Easy patch, but want some confirmation that getting an
empty column list in this method is by design and root cause is not somewhere
else.
