Subject [jira] Updated: (HDFS-1359) HDFS federation: Add BlockPoolID to block
Date Fri, 27 Aug 2010 18:08:53 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1359?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Suresh Srinivas updated HDFS-1359:

    Attachment: HDFS-1052.patch

Attached preliminary patch makes the following changes:
# Introduces new protocol class ExtendedBlock with {{String poolId}} and {{Block block}}
# All the RPC protocol interfaces are changed to use {{ExtendedBlock}} instead {{of Block}},
with the corresponding changes to the rest of the code.

After the code review, I will rename {{ExtendedBlock}} to {{Block}}. The existing {{Block}}
which is relevant only with in the block pool will be named {{LocalBlock}}. This reduces the
size of the code to be reviewed.
