Todd Lipcon resolved HDFS-2972. ------------------------------- Resolution: Fixed Fix Version/s: HA branch (HDFS-1623) Hadoop Flags: Reviewed Committed to branch. I also tested this on a 100-node cluster. > HA: small optimization building incremental block report > -------------------------------------------------------- > > Key: HDFS-2972 > URL: https://issues.apache.org/jira/browse/HDFS-2972 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: data-node, ha > Affects Versions: HA branch (HDFS-1623) > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Priority: Minor > Fix For: HA branch (HDFS-1623) > > Attachments: hdfs-2972.txt > > > Current the incremental block report is a List. However, we only really need > to send the most recent information for each block. So, if a block becomes > RBW and is then becomes FINALIZED before the next incremental block report, > we should just report the FINALIZED replica. It's an easy change to just > switch to a map by blockid. > This is on the HA branch since HA changes the code to send RBWs in the > incremental reports, hence it's more important for maintaining performance > parity with trunk. -- This message is automatically generated by JIRA.
