To preserve the old hdfs scan functionality, we may need to preserve the
starting of the threads so the scan works correctly when use_lib_hdfs is ON.

> Reporter: Selvaganesan Govindarajan
> Assignee: Selvaganesan Govindarajan
> Priority: Major

> By making LOB to use the new implementation of HdfsClient, the use of libHdfs
> is avoided in yet another feature. This also simplifies the hdfs access
> related code in this feature.
