Hello
I have problem with running HBase performance tests from
org.apache.hadoop.hbase.PerformanceEvaluation package. I'm using version
from CDH3,
Tests are ok when argument nclients is 1, but in case of greater number,
after mappers reaching 100% I get this exception (I didn't test all
tests, but all of tested by me failed, 'scan' and 'randomRead' fail for
sure):
11/01/21 17:05:19 INFO mapred.JobClient: Task Id :
attempt_201101211442_0005_m_000000_0, Status : FAILED

Do you have any ideas how to solve this?
