Yu Li commented on HBASE-9568:
------------------------------
Another issue found:
In HRegionServer#createRegionLoad, it uses *regionName* as RegionLoad name
which later used as key of RegionLoad map, so the current
HMaster.flushedSequenceIdByRegion actually is using regionName as the key.
However, in current patch HLogSplitter is trying to get the lastFlushSeqId by
*encodedRegionName*, as shown below
{code}
while ((entry = getNextLogLine(in,logPath, skipErrors)) != null) {
byte[] region = entry.getKey().getEncodedRegionName();
+ Long lastFlushedSequenceId = -1l;
+ if (master != null) {
+ lastFlushedSequenceId = lastFlushedSequenceIds.get(region);
+ if (lastFlushedSequenceId == null) {
+ lastFlushedSequenceId = -1l;
+ try {
+ lastFlushedSequenceId = master.getLastFlushedSequenceId(region);
+ lastFlushedSequenceIds.put(region, lastFlushedSequenceId);
+ } catch (IOException e) {
+ LOG.warn("Unable to connect to the master to check " +
+ "the last flushed sequence id", e);
+ master = null;
+ }
+ }
+ }
{code}
