Amareshwari Sriramadasu commented on HADOOP-4759:
-------------------------------------------------
bq. -1 findbugs. The patch appears to introduce 2 new Findbugs warnings.
Warnings:
1. JvmRunner.runChild(JvmManager$JvmEnv) ignores exceptional return value of
java.io.File.delete()
I would like to ignore the return value, it doesn't do anything with the return
value.
2. Unread field: org.apache.hadoop.mapred.JvmManager$JvmManagerForType.tracker
:This field is never read. Consider removing it from the class.
Though tracker reference is not used anywhere in JvmManager, I don't want to
delete it from JvmManager, since it could be used later.
contrib-test failure
org.apache.hadoop.chukwa.datacollection.agent.TestAgentConfig.testInitAdaptors_vs_Checkpoint
is not related to the patch.
