HA: support separate SBN and 2NN? --------------------------------- Key: HDFS-2736 URL: https://issues.apache.org/jira/browse/HDFS-2736 Project: Hadoop HDFS Issue Type: Sub-task Components: ha Affects Versions: HA branch (HDFS-1623) Reporter: Eli Collins
HDFS-2291 adds support for making the SBN capable of checkpointing, seems like we may also need to support the 2NN checkpointing as well. Eg if we fail over to the SBN does it continue to checkpoint? If not the log grows unbounded until the old primary comes back, if so does that create performance problems since the primary wasn't previously checkpointing? -- This message is automatically generated by JIRA.
