Subject [jira] [Commented] (HDFS-2799) Trim fs.checkpoint.dir values
Date Wed, 11 Apr 2012 22:59:17 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2799?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13252023#comment-13252023

Eli Collins commented on HDFS-2799:

- Both getCheckpointEditsDirs and getCheckpointDirs need to be fixed (these are the last two
uses of getStringCollection in hdfs)
- Agree w Harsh that it should use getTrimmedStringCollection directly to be consistent with
the rest of the code
- Good test for this would be to have a test that adds space or new line to each config value
that has a csv list of directories and tries to start a mini cluster (for an example of setting
new values for directories checkout TestNameEditsConfigs)

> fs.checkpoint.dir values need to be trimmed like dfs.name.dir and dfs.data.dir values
so eg the following works. This currently results in the directory "HADOOP_HOME/?/home/eli/hadoop/dirs3/dfs/chkpoint1"
being created.
