Hi there,
Wonder if anyone has seen error like this

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
of threads or tasks, size of the row,
RS resources, configurations, etc. so any additional info would be very
helpful.
cheers,
esteban.

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
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,
