Unit testing from Eclipse, occasional delay on cluster tests from datanode
webapps errors
-----------------------------------------------------------------------------------------
Key: HBASE-1475
URL: https://issues.apache.org/jira/browse/HBASE-1475
Project: Hadoop HBase
Issue Type: Bug
Components: test
Affects Versions: 0.20.0
Reporter: Jonathan Gray
Priority: Minor
This does not happen every time I run a cluster test, but probably 75% of the
time.
