Subject [jira] Commented: (HADOOP-6302) Move FileSystem and all of the implementations to HDFS project
Date Mon, 12 Oct 2009 04:38:31 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6302?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12764543#action_12764543
] 

Sharad Agarwal commented on HADOOP-6302:
----------------------------------------

mapreduce dependency on HDFS is only runtime. Lot of tests depend on HDFS because HDFS is
the primary filesystem which is used with mapreduce. We can easily consider a case where there
may be additional tests in mapreduce which work with different filesystem implementations.
I don't see any problem in this model.

> Currently, the FileSystem and FileContext classes are in Common and the primary implementation
is in HDFS. That means that many patches span between the subprojects. I think it will reduce
the pain if we move FileSystem and the dependent classes into HDFS.
