Subject [jira] [Updated] (HDFS-3689) Add support for variable length block
Date Wed, 14 Jan 2015 21:47:34 GMT

     [ https://issues.apache.org/jira/browse/HDFS-3689?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jing Zhao updated HDFS-3689:
----------------------------
    Attachment: HDFS-3689.005.patch

After an offline discussion with [~sanjay.radia] and [~szetszwo], the 005 patch still keeps
the restriction that the source files and the target file should be in the same directory.
In this way we do not need to update the quota.

new use cases and features to be built on top of HDFS.
