Subject Re: Build failed in Jenkins: HBase-TRUNK #3719
Date Thu, 10 Jan 2013 18:54:48 GMT
Since you are looking into this Ted, consider filing a ticket with infra to
clear out any /tmp/hbase-* directories on the test host.
TestLocalHBaseCluster picks up junk left there.

This is what I get testing locally:

hbase-trunk$ mvn -PrunAllTests -PlocalTests clean test
-Djava.net.preferIPv4=true -Dtest=TestLocalHBaseCluster

 T E S T S

Running org.apache.hadoop.hbase.TestLocalHBaseCluster
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 10.76 sec
