shrinidhi-arista opened a new pull request, #8232:
URL: https://github.com/apache/hbase/pull/8232
Fix includes -
- RestoreSnapshotHelper: write a back-reference to the archive when creating
an
HFileLink Reference file, so HFileLinkCleaner knows the archived HFile is
still live.
Added test TestCloneSnapshotFromClientAfterMergingRegion which fails with
FileNotFound
exception while checking if all the hfiles referenced by cloned table are
available. Disabling and
enabling the table also causes the test to hang because of master retrying
indefinitely. The test
passes with the fix.
- HFileLinkCleaner: when evaluating a back-reference, also check for
HFileLink Reference
files (glob <hfileLinkName>.*) in the link directory — these are created by
restoreReferenceFile() and protect the archived HFile even when no
zero-byte HFileLink
file exists alongside them.
Added testHFileLinkReferenceFileProtectsArchivedHFile() which fails while
asserting that Hfile
is not cleaned up but passes with the fix.
