> for replication we create a _files in hdfs which lists the source files to be copied
over for a table/partition. _files is read in ReplCopyTask to read what files to be copied.
The File operations w.r.t to _files is not correct and we leave the files open there, which
leads to a lot of CLOSE_WAIT connections to the source Data nodes from HS2 on the replica
cluster.
