we have a c++ client, and the thrift server was installed on the
Ndatanode ®ionservers.
( from the official document we know that it is not recommended for
the thrift colocated with nn &jobtracker).
as we understand the processs from client to hbase shown below:

HI,
we use CDH 4.2.0, find that some of the regions stop spliting and
increase contiusuly under heavy load. some regions become much bigger than
the setting value(4G),reaches 46g.
any reason or bugs?
Thansk!

Hello, I have a big problem
We deleted hbase data with " hdfs dfs -rmr -skipTrash /hbase",
Is there any way to recovery the deleted date?
