Subject [jira] Commented: (HDFS-1528) First uploaded file replaces /home/hadoop directory
Date Sun, 05 Dec 2010 18:37:10 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12966996#action_12966996

Faraz Ahmad commented on HDFS-1528:
-----------------------------------

A quick work around which keeps file system intact is :
1. Create an empty directory on hdfs.
2. Then upload the input file.

>                 Key: HDFS-1528
>                 URL: https://issues.apache.org/jira/browse/HDFS-1528
>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: name-node
>    Affects Versions: 0.20.2
>         Environment: distributed file system
>            Reporter: Faraz Ahmad

> This bug shows up in the following scenario:
> 1. There is no input data on HDFS (i.e., it has been formatted recently).
> 2. Upload any single file (not directory of files) e.g., build.xml.
> 3. The original directory /user/hadoop on hdfs will change itself from directory to a
file and its contents will contain the contents of the uploaded file.
> 4. Now HDFS will have a single file /user/hadoop. 
> 5. HDFS filesystem gets corrupted and we cannot upload any more files or directories.
