Does angel support the outputPath without hdfs prefix?

[facaiy]

When path is specified without hdfs prefix, like

./bin/angel-submit \
    --action.type train \
    --angel.app.submit.class com.tencent.angel.ml.classification.lr.LRRunner  \
    --angel.train.data.path /usr/foo/data \
    --angel.save.model.path /usr/foo/model \

Angel always failed with the exception, which is really ambiguous:

Exit code: 1

So I checked all logs on yarn, and noticed that the names of output directories start with null.
