Thomas Graves commented on MAPREDUCE-2451:
------------------------------------------
For the 20.205 branch these are based on branch-0.20-security here are the
results of test-patch. The -1 for javadoc and eclipse both exists in the
branch-20-security without my change.
I didn't include any tests because this is a trivial change to the log
message. Manual test steps are below.
[exec] -1 overall.
[exec]
[exec] +1 @author. The patch does not contain any @author tags.
[exec]
[exec] -1 tests included. The patch doesn't appear to include any new
or modified tests.
[exec] Please justify why no tests are needed for
this patch.
[exec]
[exec] -1 javadoc. The javadoc tool appears to have generated 1
warning messages.
[exec]
[exec] +1 javac. The applied patch does not increase the total number
of javac compiler warnings.
[exec] [exec] +1 findbugs. The patch does not introduce any new
Findbugs warnings. [exec]
[exec] -1 Eclipse classpath. The patch causes the Eclipse classpath to
differ from the contents of the lib directories. [exec] [exec]

Manual test steps:
- modify mapred_site.xml to have the mapred.healthChecker.script.path
configuration. Have it point to a script like ~/health_check.
- modify ~/health_check to contain just something like:
#!/bin/bash
exit 0
- start the cluster and make sure every is running fine.
- modify the ~/health_check script on a tasktracker and insert the a line like:
echo -n "ERROR new string" before the exit 0 line.
- wait for tasktracker to send heartbeat back with updated health info
- look in the jobtracker log file and verify the log line looks similar to
this. This bug added the "Reason details : ERROR new string" bit.
2011-05-04 13:30:31,926 INFO org.apache.hadoop.mapred.JobTracker: Blacklisting
tracker : yourhost.com Reason for blacklisting is : NODE_UNHEALTHY Reason
details : ERROR new string
- also verify the tasktracker got blacklisted.
