[jira] [Commented] (NUTCH-2533) Injector: NullPointerException if seed URL dir contains non-file entries
[
https://issues.apache.org/jira/browse/NUTCH-2533?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16433638#comment-16433638
]
Sebastian Nagel commented on NUTCH-2533:
Nutch resp. the Hadoop
[FileInputFormat|http://hadoop.apache.org/docs/r2.8.2/api/index.html?org/apache/hadoop/mapreduce/lib/input/FileInputFormat.html]
expects either a single file or a directory containing files as input for seed
URLs. To make it recursively read input files would allow to many potential
errors, esp. if the root directory {{/}} is passed as seed directory: it
contains many special files (devices, named pipes, etc.) and you hardly have
the permissions to read the entire directory tree. But agreed: the error
message resp. stack trace isn't really informative for Nutch/Hadoop newbies.
I'll prepare a fix to improve the error message and log all non-file inputs in
the seed directory. Thanks!
