Subject Get operation slows in MR job
Date Tue, 29 Jul 2014 00:34:06 GMT
Hi there,

I have a MR job that does Get and then Put operation to a Hbase table.
For the write operation, I am using TableOutputFormat (like to the map
function in
https://github.com/larsgeorge/hbase-book/blob/master/ch07/src/main/java/mapreduce/ImportFromFile.java
).
The write is pretty fast, 200K requests/sec.

But the read operations are slow, like 2K requests/sec. I wonder if anyone
has recommendation on how to improve read operations. I am using batched
Gets already.

thanks in advance
