Subject Exceptions were shown when 5 billions of records were being populated into HBase on a single node
Date Thu, 17 Dec 2009 22:38:15 GMT
Hi there:

I tried to populate data into a table. HBase is set up in a single node
mode.

Things started fine until 5 mins after the data population started.

Here is the exception:
Exception in thread "main"
org.apache.hadoop.hbase.client.RetriesExhaustedException: Trying to contact
region server 10.0.176.64:39045 for region Genome,,1261087437258, row

but failed after 10 attempts.

Can anybody let me know how to fix it?
Thanks,
Xueling
