Subject [jira] Commented: (HADOOP-1887) ArrayIndexOutOfBoundsException with trunk
Date Mon, 17 Sep 2007 18:20:43 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12528104
] 

Raghu Angadi commented on HADOOP-1887:
--------------------------------------

bq. The FileNotFound exception in the namenode log is expected. A client is invoking isDir()
to determine if the path is a directory. The deprecated isDir() call is invoke getFileStatus
but the file does not exist yet, hence the exception in the namenode log.

File does exist, right? Otherwise, how does client even know the path to use for isDir()?

> How to reproduce : 
> # Run a DFS cluster (single node is fine). 
> # Start writing a file but do not close it : {{cat | bin/hadoop dfs -copyFromLocal -
/dir/file}} does that.
> # goto /dir on Hadoop webui or do {{bin/hadoop fs -cat /dir/file}}.
> This is mostly related to HADOOP-1708.
