          String newLocalDirs = conf.get(contextCfgItemName);
          if (!newLocalDirs.equals(savedLocalDirs)) {
          				int minDiskFreeThresholdMb = conf.getInt("hadoop.min.local.disk.freespace.threshold", 1024);
          

          Here newLocalDirs will become null and it'll throw NPE..

          I did fix like this..

            String newLocalDirs = conf.get(contextCfgItemName);
          			if (null == newLocalDirs) {
          				throw new IOException("dfs.client.buffer.dir not configured");
          			}
                if (!newLocalDirs.equals(savedLocalDirs) ) {
                  localDirs = StringUtils.getTrimmedStrings(newLocalDirs);

          Hi,

          Does this functionally depend on HADOOP-8437 as per your earlier comment? I don't seem to see the patch relying on it.

          The parameter dfs.client.buffer.dir appears very, very outdated to me, and whatever is using that must be removed or changed to use a new config name. We no longer require buffer directories in DFS writes as we used to in ancient versions of HDFS.

          Comments on patch:

          +	  if (null == newLocalDirs) { 
          +        throw new IOException(contextCfgItemName + " not configured"); 
          +      }
          

          Indentation issue near if

          + fail("not throwing the exception"); 
          

          Same comment about this as on HADOOP-8437. Please apply a better failure message that makes it easier for us to debug it if it ever fails in future someday.

          +      assertEquals("Incorrect exception message", 
          +          CONTEXT+" not configured", e.getMessage()); 
          

          Probably wanna space between the strings concatenated here.

          Thanks!
