Uma Maheswara Rao G commented on HDFS-2291: ------------------------------------------- {quote} One thought is to use a third, dedicated checkpointing node in addition to the active and standby nodes. {quote} Introducing new nodes may create overheads in setting up the clusters. we can always think to reduce the cluster complexities to create setups. {quote} Another option would be to make the standby capable of also performing the function of checkpointing. {quote} IMO , standby can do checkpointing job. what do you say Aaron? > HA: Checkpointing in an HA setup > -------------------------------- > > Key: HDFS-2291 > URL: https://issues.apache.org/jira/browse/HDFS-2291 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: name-node > Affects Versions: HA branch (HDFS-1623) > Reporter: Aaron T.
