Description

If a config file is set up as the following, which is shown on the cas-curator user guide:

[joshuaga@jpl-esg mp3extractor]$ cat mp3PythonExtractor.config
<?xml version="1.0" encoding="UTF-8"?>
<cas:externextractor xmlns:cas="http://oodt.jpl.nasa.gov/1.0/cas">
<exec workingDir="">
<extractorBinPath>
/home/joshuaga/extractors/mp3extractor/mp3PythonExtractor.py
</extractorBinPath>
<args>
<arg isDataFile="true"/>
</args>
</exec>
</cas:externextractor>

tomcat's catalina.out log file can have a warning such as:

WARNING: IOException running met extraction: commandLine: [\ /home/joshuaga/extractors/mp3extractor/mp3PythonExtractor.py\ \ \ \ \ \ \ /home/joshuaga/staging/products/mp3/Bach-SuiteNo2.mp3 ]: Message: java.io.IOException: \ /home/joshuaga/extractors/mp3extractor/mp3PythonExtractor.py\ \ \ \ \ \ \ : not found

Which shows that the command being run when using the extractor is adding spaces with escape sequences which gives the not found error shown.

The workaround is simply:

<?xml version="1.0" encoding="UTF-8"?>
<cas:externextractor xmlns:cas="http://oodt.jpl.nasa.gov/1.0/cas">
<exec workingDir="">
<extractorBinPath>/home/joshuaga/extractors/mp3extractor/mp3PythonExtractor.py</extractorBinPath>
<args>
<arg isDataFile="true"/>
</args>
</exec>
</cas:externextractor>
