Zhihong Yu commented on HBASE-4254:
-----------------------------------
Interesting idea.
{code}
+ waitUntilNotUnderConstruction(dfsCluster,p.toUri().getPath());
+ readRowsFromHLog(p,loggedRows);
{code}
How do we know that the second call to readRowsFromHLog() wouldn't result in
IOE ?
{code}
+ do {
+ Thread.sleep(100);
+ blocks = (LocatedBlocks)
getBlockLocations.invoke(null,cluster.getNameNode(),testPath,0,1);
+ } while (blocks.isUnderConstruction());
{code}
Do we need some timeout for the above wait ?
Once the logic in the patch gets confirmation from various experts (including
Todd), we can consider moving it to a better place.
I would also like to refer to https://issues.apache.org/jira/browse/HDFS-2991
which we encountered in staging environment.
For 0.23.2-SNAPSHOT, we should have the fix.
