hadoop archive impact on hbase performance

Dear All,

Recently I observe that whenever Hadoop archive is running, all HBase insert (put) will slow down, from average 0.001 to 0.023, that is 23x times slower.

I wonder if there a way to slow down the archive process? Like restrict read / write buffer?

One of the restriction already implemented is to restrict only 1 map running using fair scheduler.

Best regards,
Henry
