[jira] [Commented] (MAHOUT-1142)
TestDistributedLanczosSolverCLI.testDistributedLanczosSolverEVJCLI is
broken with Hadoop 0.23.5
[ https://issues.apache.org/jira/browse/MAHOUT-1142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13556949#comment-13556949 ]
Jimmy Xiang commented on MAHOUT-1142:
-------------------------------------
This test is broken due to HADOOP-8906.
The issue is that if the path pattern is something like "/parent_path/file/*", the original FileSystem#globStatus will return the status of the file "/parent_path/file". The new one (HADOOP-8906) returns nothing since "file" is a file, not a folder.
