HIVE_AUX_JARS_PATH interferes with startup of Hive Web Interface
----------------------------------------------------------------

                 Key: HIVE-1294
                 URL: https://issues.apache.org/jira/browse/HIVE-1294
             Project: Hadoop Hive
          Issue Type: Bug
          Components: Web UI
    Affects Versions: 0.5.0
            Reporter: Dilip Joseph
            Priority: Minor


The Hive Webserver fails to startup with the following error message, if 
HIVE_AUX_JARS_PATH environment variable is set (works fine if unset).   

$ build/dist/bin/hive --service hwi
Exception in thread "main" java.io.IOException: Error opening job jar: -libjars
       at org.apache.hadoop.util.RunJar.main(RunJar.java:90)
Caused by: java.util.zip.ZipException: error in opening zip file
       at java.util.zip.ZipFile.open(Native Method)
       at java.util.zip.ZipFile.<init>(ZipFile.java:114)
       at java.util.jar.JarFile.<init>(JarFile.java:133)
       at java.util.jar.JarFile.<init>(JarFile.java:70)
       at org.apache.hadoop.util.RunJar.main(RunJar.java:88)

Slightly modifying the command line to launch hadoop in hwi.sh solves the 
problem:

$ diff bin/ext/hwi.sh  /tmp/new-hwi.sh
28c28
<   exec $HADOOP jar $AUX_JARS_CMD_LINE ${HWI_JAR_FILE} $CLASS $HIVE_OPTS "$@"
---
>   exec $HADOOP jar ${HWI_JAR_FILE}  $CLASS $AUX_JARS_CMD_LINE $HIVE_OPTS "$@"
