Subject [jira] Commented: (HADOOP-4546) Minor fix in dfs to make hadoop work in AIX
Date Thu, 30 Oct 2008 10:55:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4546?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12643809#action_12643809
] 

Steve Loughran commented on HADOOP-4546:
----------------------------------------

although this will be hard to test on non AIX systems, if the parsing is decoupled from the
execution, you could have junit tests that verify you can parse AIX output just by handing
static strings of df output to the parser. this would keep coverage up and catch regressions
early.

> HDFS uses df command to get the disk space. The output format of df command is different
in AIX compared to Linux and Solaris. Checking the OS type and then reading the df output
as per the format will fix this issue and thus allows hadoop to be fully functional in AIX
environment.
