------------------------------------------------------------
# I think Kylin should clean up these files at the end of the task just like
any other garbage file，and hdfs will not automatically cleanup “/tmp”
folder。HDFS administrators have been complaining that Kylin is generating junk
files for no reason:(.
# "hbase.fs.tmp.dir" has default values，but Kylin didn't load it correctly and
set “/tmp”，I think this is a bug
# "fs.deleteOnExit(partitionsPath)" at HFileOutputFormat3.java:536，this method
wants to clean up these tmp files, but it will never take effect in this
situation，I think we should improve this.
