You mean this is the normal action, this wouldn't cause the process blocked
long time?

Subject: Re: Re: Java Client Write Data blocked
this is the piece of code related to your stack trace:
// check periodically to see if a system stop is requested
if (Store.closeCheckInterval > 0) {
bytesWritten += kv.getLength();
if (bytesWritten > Store.closeCheckInterval) {
bytesWritten = 0;
isInterrupted(store, writer);
}
}
It seems something asked the region to close. Can you check the same time in
the master to see if the balancer get started? Your region was compacting. And
I think that if balancer start while region is compacting, balancer ask the
compaction to stop.
This is most probably not what caused your writes to be stuck.

Thanks JM.
But the log is too big, How can I post the log file?
The query from HBase is slower too.
The Network is OK, I'm sure.
Does GC have the log file ? And how to know the swap?
Sorry, I'm rookie.

Any logs?
Gargabe collection on the server side? Network issue? Swap?
Please share your master and region servers logs so we can provide feedback.

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!
