Junping Du commented on HDFS-2832: ---------------------------------- The unit test failure may due to no cleanup as I still see old "48" version in edit xml in Jenkins test log (my local env is OK) Filed HDFS-5510 to fix a findbug warning. The audit warning can be ignored. > Enable support for heterogeneous storages in HDFS > ------------------------------------------------- > > Key: HDFS-2832 > URL: https://issues.apache.org/jira/browse/HDFS-2832 > Project: Hadoop HDFS > Issue Type: New Feature > Affects Versions: 0.24.0 > Reporter: Suresh Srinivas > Assignee: Suresh Srinivas > Attachments: 20130813-HeterogeneousStorage.pdf, H2832_20131107.patch, > editsStored, h2832_20131023.patch, h2832_20131023b.patch, > h2832_20131025.patch, h2832_20131028.patch, h2832_20131028b.patch, > h2832_20131029.patch, h2832_20131103.patch, h2832_20131104.patch, > h2832_20131105.patch, h2832_20131107b.patch, h2832_20131108.patch, > h2832_20131110.patch, h2832_20131110b.patch, h2832_20131111.patch, > h2832_20131112.patch, h2832_20131112b.patch > > > HDFS currently supports configuration where storages are a list of > directories. Typically each of these directories correspond to a volume with > its own file system. All these directories are homogeneous and therefore > identified as a single storage at the namenode. I propose, change to the > current model where Datanode * is a * storage, to Datanode * is a collection > * of strorages. -- This message was sent by Atlassian JIRA (v6.1#6144)
