TestBalancer waits forever, errs without giving information
-----------------------------------------------------------
Key: HDFS-1808
URL: https://issues.apache.org/jira/browse/HDFS-1808
Project: Hadoop HDFS
Issue Type: Bug
Components: data-node, name-node
Affects Versions: 0.22.0
Reporter: Matt Foley
Assignee: Matt Foley
In three locations in the code, TestBalancer waits forever on a condition.
Failures result in Hudson/Jenkins "Timeout occurred" error message with no
information about where or why. Need to replace with TimeoutExceptions that
throw a stack trace and useful info about the failure mode.
In waitForHeartBeat(), it is waiting on an exact match for a value that may be
coarsely quantized -- i.e., significant deviation from the exact "expected"
result may occur. Replace with an allowed range of result.
