[WIP]Make default replication as 3 for direct write HDFS mode
Problem:
At present if we enable direct write on HDFS, data is written with replication of 1 which can cause dataloss.
Solution: Use default replication as 3 and also make it configurable so that user can tune based on the need

please get the initial replication from hdfs default, like below

short replication = FileFactory.getDefaultReplication(fileName, fileType);

We only need to modify Line361, use this value to replace 1.

There is no need to add a property for the default replicator. We can read it from HDFS system property.
