Question

I have a hadoop job which includes some spring beans. Also, in the spring context file, there is a PropertyPlaceholderConfigurer named app.properties.

This app.properties is within the jar file, the idea is remove it from the jar file in order to change some properties without re compile.

I tried the -file option, the -jarlibs option but neither worked.

Any ideas?

Answer 1

What I did was:

• Subclass the PropertyPlaceholderConfigurer
• Override loadProperties method

• If there is a custom System.getProperty(“hdfs_path”)

      try {
          Path pt = new Path(hdfsLocationPath);
          FileSystem fs = FileSystem.get(new Configuration());
          BufferedReader br = new BufferedReader(new InputStreamReader(fs.open(pt)));
          props.load(br);
      } catch (Exception e) {
          LOG.error(e);
      }
  

works like a charm …
