Sahil Takiar commented on HIVE-18865:
-------------------------------------
Just curious, do you mean a codescan tool was used to generate these warnings?
What codescan tool was used?
> Check filesystem calls return value (codescan)

> Key: HIVE-18865
> URL: https://issues.apache.org/jira/browse/HIVE-18865
> Project: Hive
> Issue Type: Bug
> Reporter: Thejas M Nair
> Priority: Major
>
> There are a few places where return value of certain filesystem operations
> are not being checked.
> Hive should at the very least log these failures.
> 1. Overview : The method saveDir() in BeeLineOpts.java ignores the value
> returned by mkdirs() on line 174, which could cause the program to overlook
> unexpected states and conditions.
> In the file BeeLineOpts.java similar issues were on line numbers 174
> 2. Overview : The method compile() in CompileProcessor.java ignores the value
> returned by mkdir() on line 226, which could cause the program to overlook
> unexpected states and conditions.
> In the file CompileProcessor.java similar issues were on line numbers 234, 226
> 3. Overview : The method deleteTmpFile() in FileUtils.java ignores the value
> returned by delete() on line 939, which could cause the program to overlook
> unexpected states and conditions.
> In the file FileUtils.java similar issues were on line numbers 939
