Subject Short circuit reads and hadoop
Date Fri, 11 Oct 2013 15:12:20 GMT
I came across this interesting JIRA in hadoop

In essence, it allows us more control over where blocks are placed.

A BlockPlacementPolicy to optimistically write all blocks of a given
index-file into same set of datanodes could be highly helpful.

Co-locating shard-servers and datanodes along with short-circuit reads
should improve greatly. We can always utilize the file-system cache for
local files. In case a given file is not served locally, then shard-servers
can use the block-cache

Do you see some positives in such an approach?
