-----------------------------
Summary: DistributedLogReplay drops edits when ITBLL 125M
Key: HBASE-14028
URL: https://issues.apache.org/jira/browse/HBASE-14028
Project: HBase
Issue Type: Bug
Components: Recovery
Affects Versions: 1.2.0
Reporter: stack
Testing DLR before 1.2.0RC gets cut, we are dropping edits.
Issue seems to be around replay into a deployed region that is on a server that
dies before all edits have finished replaying. Logging is sparse on sequenceid
accounting so can't tell for sure how it is happening (and if our now
accounting by Store is messing up DLR). Digging.
I notice also that DLR does not refresh its cache of region location on error
-- it just keeps trying till whole WAL fails.... 8 retries...about 30 seconds.
We could do a bit of refactor and have the replay find region in new location
if moved during DLR replay.
