-------------------------------------------
Hi [~szetszwo] and [~vinayrpet] thnks for review comments.
The below are my understanding
# In Har filesystem for index and master we are currently using harcoded value
5.
# For Part files the replication value will be default 3 always rt?
Wanted to make replication for {{part,index,masterindex}} to be
configurable.The only parameter available
for replication was {{-r}}. The same parameter used for {{srcfiles}}. I didn't
want to add one more parameters.
Thts the reason have used the same parameter for index and master.
*To implement patch*
{{option 1}} could be define a new parameter.
For part,master and index new parameter {{-hr}} short for har replication??
[~vinayrpet] sorry missed part files earlier will set replication for that
too.About not setting replication for {{srcfiles}}
But for source file and output files(part,index,master) if someone want to set
different replication values?
{{option 2}} could be user defined replication {{-r}} for {{master,index,part}}
and parameter {{-sr}} for source file replication . Default value for both set
as 3.
[~szetszwo] and [~vinayrpet] Does this sound good ?? Please correct me if i am
wrong.
My choice {{option 2}}
> Hadoop archives command should use configurable replication factor when
> closing

> {{HadoopArchives#HArchivesReducer#close}} uses hard-coded replication factor.
> It should use {{repl}} instead, which is parsed from command line parameters.
> {code}
> // try increasing the replication
> fs.setReplication(index, (short) 5);
> fs.setReplication(masterIndex, (short) 5);
> }
