[jira] [Resolved] (HDFS-4991) HDFSSeek API fails to seek to
position when file is opened in write mode.
[ https://issues.apache.org/jira/browse/HDFS-4991?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Harsh J resolved HDFS-4991.
---------------------------
Resolution: Invalid
First off, please do not use the JIRA as a Q&A medium. The HDFS project provides and maintains a development list at hdfs-dev@hadoop.apache.org you should mail to with such questions. Only file valid issues on the JIRA please.
Onto your question, HDFS has no random-write features, it does not support it yet, hence there exists no API. If you plan to add such a feature, a design document for your implementation idea and discussion on the hdfs-dev@ lists is very welcome. Merely adding an API will not solve this - you will need to understand why its a limitation at the architecture level currently first.
Resolving as invalid. Please use lists for general Q&A.

> Hi,
> hdfsSeek API fails to seek to position when file is opened in write mode. I studied in documentation that hdfsSeek is only supported when file is opened in read mode.
> We have a requirement of replacing the file resided on hadoop environment.
> Is there any possibility of having HDFSSeek to be supported when file is opened in write mode?
> Regards,
