Hi there,
To get good read performance, should the region server be installed on
every data node? (Thinking about data locality here)
thanks

Hi there
I have a use-case where I need to do a read to check if a hbase entry
is present, then I do a put to create the entry when it is not there.
I have a script to get a list of rowkeys from hive and put them on a
HDFS directory. Then I have a MR job that reads the rowkeys and do
batch reads.
I just created a new test table today, and when trying to drop it, I got
ERROR: No serverName in hbase:meta for
p_hashes,,1407880525015.6fe0bbb6e5a6f614891e7c1c5901c70f. containing
In the hbase master log, it said

Hi there,
I have a Hbase MR job that reads data from HDFS, do a Hbase Get, and then
do some data transformation. Then I need to put the data back to Hbase as
well as write data to a HDFS file directory (so I can import it back into
Hive).
The current job creation logic is similar to the followin
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, 200
