Subject Re: how to use hbase with eclipse?
Date Tue, 20 Oct 2009 04:43:07 GMT
Hi,

What do you mean nothing happened? Did your program finish running
without error but no record inserted to the table? Or did it get
stalled when it try to connect to HBase?

If you're having the latter case, let your program to run for a few
minutes and you'll eventually see some error messages. Make sure you
didn't leave the table disabled; it will cause your program to pause
for a few minutes (but you will get RegionOfflineException after a few
minutes.)

Thanks,
