-----------------------------------
Resolution: Fixed
Fixed in HADOOP-5476
> SequenceFile.Reader constructor leaking resources
> -------------------------------------------------
>
> Key: MAPREDUCE-1504
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1504
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Reporter: Zheng Shao
>
> When {{SequenceFile.Reader}} constructor throws an {{IOException}} (because
> the file does not conform to {{SequenceFile}} format), we will have such a
> problem.
> The caller won't have a pointer to the reader because of the {{IOException}}
> thrown.
> We should call {{in.close()}} inside the constructor to make sure that we
> don't leak resources (file descriptor and connection to the data node, etc).
