Peter Slawski updated HIVE-8525:
--------------------------------
Attachment: HIVE-8525.1.patch
> Add jasper-compiler-jdt runtime dependency to hwi
> -------------------------------------------------
>
> Key: HIVE-8525
> URL: https://issues.apache.org/jira/browse/HIVE-8525
> Project: Hive
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 0.13.1
> Reporter: Peter Slawski
> Attachments: HIVE-8525.1.patch
>
>
> Without the jasper-compiler-jdt*.jar in hive/lib, the HWI service cannot
> compile jsp files.
> I've also noticed that this is mentioned in HIVE-5132 and HIVE-6912 in order
> to get HWI working. But, no code change or documentation were made in light
> of this.
> It seems reasonable to include jasper-compiler-jdt as a dependency in
> hwi/pom.xml. Are there any reasons not to do so?
> ------
> I had to do the following to reproduce this error:
> 1. Generate war file (HIVE-8400)
> 2. Fix bin/ext/hwi.sh script to make HWI_WAR_FILE be relative to HIVE_HOME
> 3. Run `hive --service hwi`
> 4. Go to http://localhost:9999/hwi/
> 5. A 500 Error appears:
> {code}
> HTTP ERROR 500
> Problem accessing /hwi/. Reason:
> Unable to find a javac compiler;
> com.sun.tools.javac.Main is not on the classpath.
> Perhaps JAVA_HOME does not point to the JDK.
> It is currently set to "/usr/java/jdk1.7.0_65/jre"
