Subject Re: Problem with flushing and identical timestamps
Date Wed, 27 Jan 2010 02:30:37 GMT
Hi,

There are 3 zookeeper servers(4 core, 12G RAM), 10 Region servers (4 core,
12G RAM) in my cluster.
900 regions are in HBase now.
I don't know why the RetriesExhaustedException raised.
Any suggestions?

org.apache.hadoop.hbase.client.RetriesExhaustedException:
org.apache.hadoop.hbase.client.RetriesExhaustedException: Trying to contact
region server Some server, retryOnlyOne=true, index=0, islastrow=true,
tries=9, numtries=10, i=19, listsize=20,
region=FRPF-MAINPD_ID,,1264583412962 for region
FRPF-MAINPD_ID,,1264583412962, row 'XRD_AE32739-01.001036q5gak_kd3gxd', but
failed after 10 attempts.
Exceptions:
