chenglei updated PHOENIX-3850:
------------------------------
Description:
When the RegionServer starts, I always find the region logs "Found some
outstanding index updates that didn't succeed during WAL replay - attempting to
replay now." That is because in following Indexer.postOpen method, the LOG.info
in line 528 is before the if statement in line 531, so the method alway log
"Found some outstanding index updates that didn't succeed..." no matter whether
there are outstanding index updates.
{code}
520 @Override
521 public void postOpen(final ObserverContext<RegionCoprocessorEnvironment>
c) {
522 Multimap<HTableInterfaceReference, Mutation> updates =
failedIndexEdits.getEdits(c.getEnvironment().getRegion());
523
524 if (this.disabled) {
525 super.postOpen(c);
526 return;
527 }
528 LOG.info("Found some outstanding index updates that didn't succeed during"
529 + " WAL replay - attempting to replay now.");
530 //if we have no pending edits to complete, then we are done
531 if (updates == null || updates.size() == 0) {
532 return;
533 }
534
535 // do the usual writer stuff, killing the server again, if we can't
manage to make the index
536 // writes succeed again
537 try {
538 writer.writeAndKillYourselfOnFailure(updates, true);
539 } catch (IOException e) {
540 LOG.error("During WAL replay of outstanding index updates, "
541 + "Exception is thrown instead of killing server during
index writing", e);
542 }
543 }
{code}
> Indexer.postOpen should not always log "Found some outstanding index updates
> that didn't succeed"
