Subject [jira] [Updated] (HDFS-2148) Address all the federation TODOs
Date Wed, 04 Jan 2012 18:01:40 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2148?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Eli Collins updated HDFS-2148:

    Target Version/s: 0.23.1
       Fix Version/s:     (was: 0.24.0)

Looks like there are 4 issues remaining:

1. NNThroughputBenchmark doesn't support federation
2. There's a scalability issues with BlockPoolSlice ("a thread per DU is needed")
3. FSDataSet#checkDirs is not correctly synhronized
4. NameNode#getAddress doesn't do the right thing?

Seems like 3 should be fixed in 23.x.  Are 2 and 3 issues that need to be addressed as well?

 We should have jiras for these and address the issues.
