Michele (aka pirroh) Catasta commented on HADOOP-2366: ------------------------------------------------------ Is there something I should do to trigger again the Hudson build with the new patch? > Space in the value for dfs.data.dir can cause great problems > ------------------------------------------------------------ > > Key: HADOOP-2366 > URL: https://issues.apache.org/jira/browse/HADOOP-2366 > Project: Hadoop Common > Issue Type: Bug > Components: conf > Reporter: Ted Dunning > Assignee: Michele (aka pirroh) Catasta > Attachments: HADOOP-2366-trimmed.patch, HADOOP-2366.patch > > > The following configuration causes problems: > <property> > <name>dfs.data.dir</name> > <value>/mnt/hstore2/hdfs, /home/foo/dfs</value> > <description> > Determines where on the local filesystem an DFS data node should store its > bl > ocks. If this is a comma-delimited list of directories, then data will be > stor > ed in all named directories, typically on different devices. Directories > that > do not exist are ignored. > </description> > </property> > The problem is that the space after the comma causes the second directory for > storage to be " /home/foo/dfs" which is in a directory named <SPACE> which > contains a sub-dir named "home" in the hadoop datanodes default directory. > This will typically cause the user's home partition to fill, but will be very > hard for the user to understand since a directory with a whitespace name is > hard to understand. > My proposed solution would be to trimLeft all path names from this and > similar property after splitting on comma. This still allows spaces in file > and directory names but avoids this problem. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
