> Key: HIVE-1884
> URL: https://issues.apache.org/jira/browse/HIVE-1884
> Project: Hive
> Issue Type: Bug
> Components: CLI, Metastore, Query Processor, Server Infrastructure
> Affects Versions: 0.3.0, 0.4.0, 0.4.1, 0.5.0, 0.6.0
> Environment: Hive 0.6.0, Hadoop 0.20.1
> SUSE Linux Enterprise Server 11 (i586)
> Reporter: Mohit Sikri
> Assignee: Chinna Rao Lalam
> Attachments: HIVE-1884.1.PATCH, HIVE-1884.2.patch

> h3.There are couple of resource leaks.
> h4.For example,
> In CliDriver.java, Method :- processReader() the buffered reader is not
> closed.
> h3.Also there are risk(s) of resource(s) getting leaked , in such cases we
> need to re factor the code to move closing of resources in finally block.
> h4. For Example :-
> In Throttle.java Method:- checkJobTracker() , the following code snippet
> might cause resource leak.
> {code}
> InputStream in = url.openStream();
> in.read(buffer);
> in.close();
> {code}
> Ideally and as per the best coding practices it should be like below
> {code}
> InputStream in=null;
> try {
> in = url.openStream();
> int numRead = in.read(buffer);
> }
> finally {
> IOUtils.closeStream(in);
> }
> {code}
> Similar cases, were found in ExplainTask.java, DDLTask.java etc.Need to re
> factor all such occurrences.
