In class org.apache.mahout.text.SequenceFilesFromDirectory line 96 the following additional parameter should be inserted into the reflection call of the ctor: "charset"

Raises Error:

pathFilter = constructor.newInstance(conf, keyPrefix, options, writer, fs);

Fix:

pathFilter = constructor.newInstance(conf, keyPrefix, options, writer, charset, fs);
