data insertion problem
Hello All,
I'm trying to use HBase to load 40G log data. But after loading 200M data,
it kept outputting the following messages and got stuck. Even the HBase
shell could not work with outputting the same error message. Have you ever
met such kind of problem?

Ray,
These are normal messages, it means that the region split and it`s searching
for the daughter region. Could you give either more debug info or see if it
fails on an exception after that?
Other useful information would be :
Hadoop/HBase versions
Number of machines
Their CPU and memory
How you configured them in regards to namenode, master, datanodes,
regionservers
What kind of insertion tool you use (MapReduce, HBase client API, Thrift,
etc)
Thx,
J-D
