Java Client Write Data blocked

Hi, All!

I need help!

I run the java client to write 3million data into HBase,

but when wrote almost 1 million, the process was blocked without any exception.

Does anyone know the possible reason? So i can find the solution.

Thanks All! 

By the way, the HBase Version is 0.94.6-cdh4.5.0!

Thanks again!

Look at when your data injection stopped, and look at the logs close to
that date and see if there is exceptions of anything. You can paste part of
those logs into pastebin.com and post the link here.

You might want to run some Performance Evaluation tests against your
cluster to see if it gives expected results...
