[jira] Updated: (HADOOP-6257) Two TestFileSystem classes are
confusing hadoop-hdfs-hdfwithmr
[ https://issues.apache.org/jira/browse/HADOOP-6257?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Philip Zeyliger updated HADOOP-6257:
------------------------------------
Attachment: HADOOP-6257.patch
Trivial rename.
BTW, the conflict showed up in the recent HADOOP-6231. And I ran into it because hadoop-hdfs-hdfswithmr-test's driver was finding the wrong TestFileSystem.
{code}
$ bin/hadoop jar lib/hadoop-hdfs-hdfswithmr-test-0.21.0-dev.jar

An example program must be given as the first argument.
Valid program names are:

> I propose to rename hadoop-common/src/test/core/org/apache/hadoop/fs/TestFileSystem.java -> src/test/core/org/apache/hadoop/fs/TestFileSystemCaching.java. Otherwise, it conflicts with hadoop-hdfs/src/test/hdfs-with-mr/org/apache/hadoop/fs/TestFileSystem.java.
