Subject SplitLogManager issue
Date Thu, 26 Sep 2013 02:31:10 GMT
I use importtsv import data into HDFS, but during the power outage.
Horrible, and then I re-import the data.(hbase 0.94)

the exception
org.apache.hadoop.hbase.client.NoServerForRegionException: Unable to find
region for data2,04684015,99999999999999 after 10 tries.

I look HMaster logs as follows:
